MHT CET
MHT CET 2012
A
inductance and resistance are both high
B
inductance and resistance are both low
C
inductance very high and resistance negligible
D
inductance low and resistance high
Solution:
The power consumption in an AC circuit is zero when circuit contains only inductance or capacitance. So, for the given option when inductance is very high and resistance is negligible, then power consumed is zero.
