Power loss in `AC` circuit will be minimum whenA. Inductance is high, resistance is highB. Inductance is low, resistance is highC. Inductance is low, resistance is lowD. Inductance is high, resistance is low |

Answer» Correct Answer - D `l = (V)/(sqrt(R^(2) + (omega L)^(2)))` power loss `= l^(2) R = (V^(2) R)/(R^(2) + (omega L)^(2)) = (V^(2))/(R + (omega^(2) L^(2))/(R ))` For minimum power loss, resistance should be low and inductance should be high. |
