A student connects a long air cored - coil of manganin wire to a 100 V D.C. supply and records a current of 25 amp. When the same coil is connected across 100 V. 50 Hz A.C. the current reduces to 20 A , the reactance of the coil is :-

A current of 4 A flows in a coil when it is connected to a 12V dc source. When the same coil is connected to an a.c. source (12 V, 8 Hz), a current of 2.4 A flows in the coil. Calculate coefficient of self inductance (L) of the coil.

Assertion: If an inductor coil is connected to DC source, the current supplied by it is I_(1) . If the same coil is connected with an AC source of same voltage. Then current is I_(2) , then I_(2) lt I_(1) . Reason: In AC circuit, inductor coil offers more resistance.
