What is the wattage of a 120 V appliance on a 20 amp circuit?

To find the wattage of a 120 V appliance on a 20 amp circuit, you can use the formula for electrical power, which is:

Power (watts) = Voltage (volts) × Current (amps)

In this case, the voltage is 120 volts and the current is 20 amps. Plugging these values into the formula gives:

Power = 120 V × 20 A = 2400 watts.

This calculation shows that a 120 V appliance operating on a 20 amp circuit requires 2400 watts of power. It is essential to understand this relationship between volts, amps, and watts in electrical systems for proper circuit design and ensuring safety when using electrical devices.
