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                                          [AIEEE 2004]

A) \[50V\]

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

C) \[100V\]

D) 0

Correct Answer: D

Solution :

[d] 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.
