The average power dissipated in a pure inductor of inductance 
when an ac current is passing through it, is
A
B
C
D
Zero
Text Solution
Verified by ExpertsThe correct answer is:
D
In a pure inductor, the average power dissipated when an alternating current (AC) flows through it is given by the formula:
Average Power (P) = 0
The reason for this is that the current and the voltage in a pure inductor are out of phase by 90 degrees. Thus, the power factor cos(90°) is zero, resulting in zero average power over a full cycle. Therefore, the correct answer is option D.
