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

100V
50√2 V
50V
0V (zero)

Correct answer: 0V (zero)

Solution

In an LCR series circuit, the voltages across the inductor (L) and capacitor (C) are equal in magnitude but opposite in phase, resulting in them canceling each other out when combined. Therefore, the voltage across the LC combination is zero.
