In an `AC` circuit the reactance of a coil is `sqrt(3)` times its resistance, the phase difference between the voltage across the current through the coil will beA. `pi//3`B. `pi//2`C. `pi//4`D. `pi//6` |
Answer» Correct Answer - A `tan varphi=(X_(L))/R =(sqrt(3)R)/Rimplies sqrt(3) implies varphi=60^(@)=pi//3` |
