AIIMS 2008 Physics Inductance MCQ Question
Type: MCQ-numerical-Hard-Class 12
When 100 V d.c. is applied across a coil, a current of 1 Å flows through it. When 100 V a.c. of 50 Hz is applied to the same coil only 0.5 Å flows. The inductance of the coil is
A
0.55 H
B
5.5 mH
C
0.55 mH
D
55 mH
Correct Answer
Option A
Detailed Explanation
For dc, V = IR (R is resistance of inductor) 100 = 1 x R => R = 100 Ω.
