STANDARD Physics Impedance MCQ Question
Type: MCQ-conceptual-Medium
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
A
series LR
B
series RC
C
series LC
D
series LCR
Correct Answer
Option A
Detailed Explanation
In a DC circuit, the current is determined by resistance, while in an AC circuit, it is determined by impedance. The given conditions imply that the circuit has an inductor in series with a resistor, as the impedance is higher in AC due to the inductive reactance.
