Updated: 5/27/2024

Watts, Amps, Volts.

The formula is simple:

P=VI

Power (in watts) equals volts times amps. For example a if a light bulb is powered by 110 volts and produces 60 watts you can determine that 60/110 or about .55 amps is going through the light bulb. 60=110 X 0.55 W = E x I, W = I2 x R, W = E2/R

The three variables in using watts are current (measured in amperes), voltage (measured in volts), and resistance (measured in ohms). Watts is a measure of power and can be calculated using the formula: Watts = Volts x Amperes.
