For very high frequencies, the effective impedance of the circuit (shown in the figure) will be
A
B
C
D
Text Solution
Verified by ExpertsThe correct answer is:
D
As frequency is very high. Here, reactance due to capacitance varies inversely whereas reactance due to inductor varies directly.
Then, 
So, effective circuit will be
Thus, capacitor acts as short circuit while inductor as an open circuit. Effective impedance will be 
.
