Question: The power P in an electric circuit varies jointly as the resistance R and the square of the current I. If the power is 10.0

The power P in an electric circuit varies jointly as the resistance R and the square of the current I. If the power is 10.0 W when the current is 0.500 A and the resistance is 40.0Ω, find the power if the current is 2.00 A and the resistance is 20.0Ω.
