1.     About Ragging:- Most of the students admitted to B.Tech degree in Delhi have already heard about the ragging. But note that after Supreme Courts guidelines, ragging is totally banned in all over india. If any senior forces you to do something in the name of ragging you can contact the same to anti ragging squad of college. When you enter in the college, first take a look at the notice board and note down the phone number of anti ragging squad members.

2.     About study:- There is a lot of difference between the school and college study patterns. Fact is that the study of college is less hectic than school but thing to remener is that time available is less. Don’t miss any of your lecture going regularly otherwise you will be lagged.

3.     About extra curricular activites:- First year students are highly attracted towards the extra curricular activities and attractive societies present in the college. A worth point to remember is that such activities are of no use for first year students. Burden of study in first year is far more than the worth of such activities so you are highly recommended to stay away from them.

4.     B.Tech tuitions. For Delhi based students taking admission to engineering courses may consider to join B.Tech tuitions in Delhi for Maths and Electrical Technology. Both subjects have lots of numerical problems and require greater attention. Joing B.Tech tuitions helps the students to proactively prepare for the sessional and final examination which helps them to stay in top position in the class. Undoubtedly the good percentage of marks in theory subjects is highly important for taking a good campus based placement.

5.     Tips for joining Tuitions.:- As stated earlier joing Engineering tuitions in Delhi for your difficult subjects helps you to proactively stay ahead from rest of the students from your class. We here at our academy are giving B.tech tuitions for subjects like, Electrical technology, Maths, Physics both on regular and weekend basis. You can take a demo class from us and stay assure for the good marks in sessional and final exams.

6.     Most of the B.Tech tuitions institutes in Delhi are located in west Delhi near subhash nagar metro station. One of the leading institute for giving B.Tech tuitions in Delh is Tejas Engineers academy. Here the faculty is highly trained and is giving B.Tech tuitions from last fifteen years. They have handful of experience and most of the concepts are on tips. It is helping the students to understand highly difficult concepts of engineering, that you will not be able to cover in self study.

7.     Web based tools are used in giving B.Tech tuitions in Delh to ease the learning process. Students are coming to us from far off places like, Noida, Faridabad, Gaziabad, etc it is highly helping the students.

8.     We charge lesser fees than any other B.Tech tuition institute or home tuitions. We recommend you to not go for home tuitions, as school based teachers will come to you for taking the B.Tech subjects, and they will ruin your fundamentals.

9.     Rajesh sir is taking B.Tech tuitions in Delhi for Digial signal processing and Emft for last ten years and he is currently associated with Tejas Engineers Academy. He is taking the subject from standard books like Proakis and SP seth.

1.      Update your class notes:- Regularly attend the classes and do complete your note book with all lecture notes. Hand written and self made notes are the best.

2.      Try to sit in the first row:- understanding of the lecture is more on front row compared to that on back rows.

3.      Don’t miss or bunk lectures:- Missing few or more lectures drastically disturbs the lecture rhythm and snatches our interest in the course.

4.      Pick previous papers:- From your library or from seniors try to get as many previous papers as possible to update yourself about the exam pattern. This the key to success because if you are planning to join B.Tech tuition in Delhi, then this is the most popular trick of the tutors to get the best result.

5.      Make subject teacher to know your name:- Somehow by asking queries, by calling on phone, or by asking or sending message on Whatsapp, facebook etc try to make the subject teacher know your name. This will keep in their mind that you are a good student and will give them impression while checking your answer sheets of internal exams and highly affects your internal marks.

6.      Keep yourself away from extracurricular activities:- It is observed many times that extracurricular activities are useless with respect to final exams or percentage of marks. They will distract you and keep you to force to join B.Tech tuitions in Delhi. We recommend you not indulge yourself too much in such activities and try to have distance from such things.

7.      Don’t believe on your friends:- Do not believe your friends regarding the  feedback of teachers or a subject or their preparation levels as they mostly try to misguide regarding how they are studying. They will not let you know about how they are preparing or getting some help or tuitions privately.

We have tried to guide you regarding self help in securing good marks in exam and try to avoid B.Tech tuitions in Delhi for your difficult papers.

Tejas engineers academy is a leading institute in providing all subjects B.Tech tuitions in Delhi and students come to us from far places like, Laxmi nagar, Gaziabad, Noida, Rohini, etc.

Lecture and Date:- 4^th October 2015 10: 00 AM to 12:00 PM

Topics to be covered:- Measuring instruments

Brief Details:- In this lecture we will cover Moving Coil, Moving Iron and dynamometer type of instruments.

Moving Iron instrument consists of a coil of copper having many turns. There is an iron spindle in front of the coil axis. Iron spindle is connected to weight to balance the spindle in equilibrium position. Iron spindle is also connected to a pointer which moves on a scale. Spindle is also connected to an air chamber provided with a piston. Purpose of air chamber is to provide air friction damping to the needle to avoid unnecessary oscillations of pointer.

When current is allowed to pass through the coil there exist a strong magnetic field along the axis of coil due to which iron spindle experiences magnetic attractive force towards the coil axis. When spindle moves towards the axis of coil, weight attached to the spindle provides gravitational controlling torque.

Amount of deflection produced is directly proportional to the square of electric current. Thus scale of the moving iron instruments is non uniform. Moving iron instruments are suitable for both ac as well as dc currents. Moving iron instruments are bulky in size and have high cost.

To know the more details of moving iron instruments we request you to attend our lecture for B.Tech tuitions in Delhi on 4^th October 2015 time 10:00 AM to 12 PM.

Moving coil Instruments:- A moving coil instrument is based on the fact that a current carrying coil placed in uniform magnetic field experiences a torque. There are two types of moving coil instruments, one is permanent magnet moving coil instrument while the other is dynamometer type moving coil instrument.

It consists of a rectangular coil having many turns of copper wire. It has a cylindrical soft iron core along the axis of coil. Coil is provided with a spring mechanism at its bottom. Coil is placed between the concave pole pieces of a permanent magnet. When electric current is passed through a rectangular coil then it experiences deflecting torque. It causes pointer to move on the scale. It also results in the twisting of the spring system attached to the coil. Deflection produced till equilibrium position is directly proportional to the current passing through the coil. Thus scale of moving coils instruments is uniform in nature. Tejas Engineers Academy B.Tech tuitions in Delhi for moving coil as well as moving iron types of instruments.

In case of dynamometer type of instruments there are two types of coil. One is moving coil and other is fixed coil. Fixed coil is used to produce a constant magnetic field while moving coil experiences torque due to fixed coil. Dynamometer type of instruments can be of two types. One is series magnet type and other is shunt magnet type. In series magnet type electric current through both fixed coil and moving coil is same. In shunt magnet type instrument electric current through moving coil and fixed coils are different. To complete the full details of dynamometer type of instrument come to Tejas Engineers Academy and attend B.Tech tuitions in Delhi.

Explanation:-

EMAC:- Three phase induction motors and widely used for industrial applications, these are used to drive heavy machines and rotors. They develop torque from three phase windings in which a rotating magnetic field is produced. Rotating magnetic field exists in stator. This magnetic field when acts on the rotator, causes change in magnetic flux and hence eddy currents are produced in rotor. Production of eddy currents causes rotor to move in synchronously with the rotating magnetic field, it is because of the opposing nature of eddy currents due to which they oppose the relative motion.  Its study is very important from the engineering application point of view. Slip is a very important parameter of three phase induction motor. It is defined as the fractional difference is speed of the rotating magnetic field and the rotational speed of rotor.

Signal and system:- Basic signals those are used in engineering study are :- unit step signal, unit impulse signal, unit ramp signal, sinusoidal signal, exponential signal. These signals are used in the analysis and design of various communication engineering blocks. Many operations can be performed on signals, such as time shifting, time reversal, amplitude scaling. Signals can be classified into many types such as even odd signals, deterministic and random signals, periodic and non periodic signals, causal non causal signals. These classification of signals are very important in the study of digital signal processing, communication engineering.
