What Formula Shows Relationship Between Volts, Amps and Watts?


Quick Answer

The Watts formula, P=V x I, shows the relationship between volts, amps and watts. The "P" signifies power in watts, "V" denotes voltage in volts and "I" stands for the current in amps. This formula is used in electrical calculations and can be used in conjunction with Ohm's law.

Ohm's law shows a linear relationship between the voltage and the current in an electrical circuit. It was named after German physicist Georg Ohm. Expressed as mathematical formulas V=I x R, R = V / I, I = V / R, Ohm's law uses "V" for voltage in volts, "I" for current in amps and "R" for resistance in ohms.
