Question

If a light draws 220 watts on a 120 volt circuit, how many amperes of electricity is it using?

Answer 1

Answer:yes it will use 1.67amps

Explanation:To convert electrical power to electrical current (Watts to Amps), we need to use the electrical power equation:

P = I*V

where:

P is electrical power, measured in Watts (W)

I is electrical current or amperage, measured in Amps (A).

V is electrical potential or voltage, measured in Volts (V). The standard voltage for most electrical devices is 110-120V, and upgraded voltage powerful electric devices use 220V.

Using this equation, we can convert watts directly to amps, if we know the voltage.
