Question 2

Coil 1, connected to a 100 W resistor, sits inside coil 2 . Coil 1 is connected to a source of 60 cycle per second AC current. Which statement about coil 2 is correct?
a. No current will be induced in coil 2.
b. DC current (current flow in only one direction) will be induced in coil 2.
c. AC current (current flow in alternating directions) will be induced in coil 2.
d. DC current will be induced in coil 2, but its direction will depend on the initial direction of flow of current in coil 1.
e. Both AC and DC current will be induced in coil 2.
