# A coil has a resistance of 10 Ω and an inductance of 0.4 Henry. It is connected to an AC source of 6.5 V, 30/π Hz. Find the average power consumed in the circuit.

Given: Resistance (R) = 10 Ω,

Inductance (L) = 0.4 Henry,

It is connected to an AC source (E) of 6.5 V and

Frequency (f) = 30/π Hz.

Then, Impedance (Z) of a coil is given by

Hence, the rms current will be

And

Thus, the average power consumed in the circuit will be

W
