LC DC Circuit For IIT-JEE

In which part of IIT-JEE exam LC DC Circuit related questions asked ? give sample questions of this part ?

Hey , LC DC Circuit related questions are related to Electromagnetic Induction topic of Physics section of IIT-JEE exam.

I am here giving you sample questions of EMI topic for IIT JEE exam.

The self inductance of the motor of an electric fan is 10 H. In order to impart maximum
power at 50 Hz, it should be connected to a capacitance of
2 I
( a ) 8 I' F ( b I 4 I' F ( c I 2 I' F ( d I 1 I' F

The magnetic flux linked with a coil is given by the equation t = 3t 2 + 4t + 9 Wb. The magnitude of induced emf at t = 2 sec. Is
( a 1 16 V ( b 1 9 V ( c ) 4 V ( d 1 1 V 1


1 When the current changes from + 2 A to - 2 A in 0.05 second, an e .m .f. of 8 V is induced
in a coil. The coefficient of self-induction in the coil is
( a I 0.1 H ( b) 0.2 H ( c I 0.4 H ( d ) 0.8 H

Two coils are placed close to each other. The mutual inductance of the pair of coils
depends upon
13)
( a ) currents in the coils ( b ) materials of the wires of the coils
( c ) relative position and orientation of the coils
( d ) rates at which the currents are changing in the coils

A long hollow cylindrical wire is placed parallel to the direction of uniform magnetic field
which is directed along + z-axls. Then Induced current on the surface of cylinder is
( a ) in the direction of the magnetic field
( c ) clockwise as seen from + z-axis
(b) zero
( d ) anticlockwise as seen from + z-axis

An alternating voltage E = 200 112 sin (100 t) is connected to a 1 Jl.f capacitor through
an a.c. ammeter. The reading of the ammeter shall be
( a ) 10 mA ( b ) 20 mA ( c } 40 mA d ) 80 mA
