As the frequency of an ac circuit increase, the current first increases and then decreases. What combination of circuit elements is most likely to comprise the circuit?
Text Solution
Verified by ExpertsThe correct answer is:
C
Impedance of an 
circuit is given by
The variation of 
with 
is shown in figure.
As 
increases, 
decreases and hence current increases.
At 
is minimum, current is maximum. Beyond 
increases and current decreases. Hence, the combination of circuit elements is most likely to comprise the circuit are 
and 
.
