Question

can u give me a practical explanation of current and voltage

Answer 1

Electric current is the rate of charge flow past a given point in an electric circuit, measured in Coulombs/second which is named Amperes. Current is a movement charge thru some imaginary area (transverse section of wire, for example). Voltage is equal to the work done per unit charge. Work is done by electric field.
