In the circuit shown in figure neglecting source resistance the voltmeter and ammeter reading will respectively, will be A. 0 V , 3 AB. 150 V , 3 AC. 150 V, 6 AD. 0 V, 8 A |
Answer» Correct Answer - D The voltages `underset(L)(V)` and `underset(C )(V)` are equal and opposite so, voltmeter reading will be zero. Also, R = `30Omega` , `underset(L)(X)` = `underset(C )(X)` = `25Omega` So, `I = V/sqrt R^(2) + (underset(L)(X) - underset(C )(X))^(2))` `V/R = 240/30 = 8 A` |
