Electricity equations
Calculate potential difference, power and charge flow.
Potential difference
potential difference = current × resistance
Potential difference is measured in volts (V), current in amperes (A), and resistance in ohms (Ω).
Electrical power
power = potential difference × current
Power is measured in watts (W).
Charge flow
charge = current × time
Charge is measured in coulombs (C), current in amperes (A), and time in seconds (s).
