    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)  100 V                                   

D)  0 (zero)

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.
