# Ohm’s law: A circuit has a source voltage of 50v and a current of 10a. what is the power in watts

Question: A circuit has a source voltage of 50V and a current of 10A. what is the power in watts?

Answer: 500 watts

Step by Step Solution:

From **Ohm’s law triangle** the formula for power:

P = VI

Where

V = Voltage = 50 V

I = Current = 10 A

**P = 50 * 10 = 500 W**

So that was all.
