how to distinguish dc resistance and ac resistance in cable

Answers

Answered by pintukumarmandal

i.e. capacitive and inductive reactances in DC circuits zero because there is no frequency in DC circuits, i.e. magnitude of DC current is constant. Therefore, only the original resistance of wire comes into play. Good to know: That's why the resistance offered by a wire is lower for DC than AC.
