The L-C  parallel resonant circuit 


A) has a very high impedence

B) has a very high current

C) acts as resistance of very low value

D) has zero impedance

Answer:

Option A

Explanation:

 In case of a parallel resonance L-C circuit the capacitive and inductive resistance equal to each other, the total impedance of the circuit increases to infinity meaning the circuit draws no current from the AC power source.
