How much current does a 1500W electric appliance draw in a 120V circuit?

[Jabababa]

Homework Statement

The power rating of an electric appliance is 1500 W. How much current does this appliance draw when it is used in a home electric circuit ( V= 120)?

Homework Equations

P= VI

The Attempt at a Solution

P= VI => I= P/V => I= 1500W/120V = 12.5A

Is this correct? This seems way too simple ha ha ha...so I am not sure.

If this is an early assignment on the topic, you could expect it to be simple. If this is a final assessment assignment you could be forgiven for wondering.

It probably is that simple but ...

The power rating is the maximum power that the device can draw. For example the 500W rated power supply in my PC draws a lot less in practice.

Thanks for your input CWatters, this is one of the question from my assignment so i can only work with what i have.

Yes, your calculation is correct. According to Ohm's Law, the current drawn by an electric appliance is directly proportional to the power rating and inversely proportional to the voltage. Therefore, using the equation P=VI, we can calculate the current drawn by the 1500W appliance in a 120V circuit to be 12.5A. This means that the appliance will draw 12.5 amps of current from the circuit to operate at its rated power of 1500 watts. It is important to note that this is the maximum current drawn by the appliance and may vary depending on the load and efficiency of the appliance.
