Question

1 What is the amperage rating of an electrical device that uses 12 kilowatts of electricity when operated for 6 hours in a 120-volt circuit? Formula is A=W/^ *

Answer 1

The amperage rating of the electrical device is 100 amperes.

Step-by-step explanation:

To find the amperage rating of an electrical device, you can use the formula A = W / V, where A is the amperage, W is the power in watts, and V is the voltage.

In this case, the power (W) is given as 12 kilowatts and the voltage (V) is given as 120 volts.

We need to convert the power from kilowatts to watts, so multiply 12 kilowatts by 1000 to get 12000 watts.

Now we can plug the values into the formula: A = 12000 watts / 120 volts.

This simplifies to A = 100 amperes.
