A choke is preferred to a resistance for limiting current in 
circuit because
Text Solution
Verified by ExpertsThe correct answer is:
B
A choke consists of an inductor. In for an inductor, resistance is negligible and the current lags by 
with respect to the applied voltage (in a.c.). As the power factor 
is very small, power consumed is very small. There is less wastage of power.
