Why current leads voltage in a capacitor (logic) - Khan Academy

WebDear vv5553743, I am not an expert but here is my best guess. The contradiction you have found arises from the assumption that the resistance in the circuit is equal to 0. From Ohm's Law, we know that I = V/R. But this does not make any sense because we are dividing by zero (I = V/0). This is why maximum current can flow when there is not voltage. WebAug 12, 2024 · In alternating current (AC), the direction of the current is switched, so not all the electricity passes through the load, and some power is generated just traveling back and forth between the load and the power source. This is called reactive power.
