In an LCR series AC circuit, the voltage across each of the components. L, C and R is 50 V. The voltage across the LC combination will be

A) \[50V\]                

B) \[50\sqrt{2}V\]

C)        \[100V\]              

D)        0

Correct Answer: D

Solution :

In an LCR series AC circuit, the voltage across inductor L leads the current by\[90{}^\circ \]and the voltage across capacitor C lags behind the current by\[90{}^\circ \]. Hence, the voltage across LC combination will be zero.
