Question

A circuit when connected to an AC source of
12 V gives a current of 0.2 A. The same circuit
when connected to a DC source of 12 V, gives a
current of 0.4 A. The circuit is
(1) Series LCR
(2) Series LR
(3) Series RC
(4) Series LC
Explanation is must​

Answer 1

The given circuit is Series LR circuit.

When the circuit is connected to an AC source of 12 V gives a current of 0.2 A.

When the same circuit is connected to DC source of 12 V, the current obtained is 0.4 A.

That means at zero frequency (DC source), the total resistance or impedance of the circuit reduces.

So we can say that the given circuit is a series LR circuit.

Hence, correct option is (2), Series LR circuit.

Answer 2

Answer:

Explanation:

how to prove its not an rc circuit . you just proved impedance will increase which can occur in rc circuit also
