Q. In an L – C – R series AC circuit, the voltage across each of the components. L, C and R is 50 V. The voltage across the L – C combination will be
A) 50 V
B) $50\sqrt{2}$ V
C) 100 V
D) zero
Explanation
(d) In an L – C – R 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 $L - C\ $combination will be zero.
