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(a) 50V (b) 50√2V(c) 100V (d) 0V (zero). |

Answer» Correct Option(d) zero Explanation: ln an L-C-R series AC circuit, the voltage across inductor L leads the current by 90° and the voltage across capacitor C lags behind the current by 90°. [ V = VL ~ VC = 50 - 50 = 0] Hence, the voltage across L-C combination will be zero. |
