Q1.An electron moves on a
straight line path XY as shown in the figure. The coil abcd is adjacent
to the path of the electron. What will be the direction of current, if any,
induced in the coil?

Q6.A circular coil with a
cross-sectional area of 4 cm^{2} has 10 turns. It is placed at the
centre of a long solenoid that has 15 turns/cm and a cross-sectional area of 10
cm^{2}. The axis of the coil coincides with the axis of the solenoid.
What is their mutual inductance?

Q7.In a transformer, the number of turns in the primary and the secondary are 410 and 1230 respectively. If the current in primary is 6A, then that in the secondary coil is

Q9.In an electrical circuit, R,
L, C and AC voltage source are all connected in series. When L is
removed from the circuit, the phase difference between the voltage and current
in the circuit is π /3 . Instead, if C is removed from the circuit,
the phase difference is again π / 3 . The power factor of the circuit is

Q10.In a series RL circuit, the resistance and inductive reactance are the same. Then the phase difference between the voltage and current in the circuit is
