Question 960674: P=I^2(20) represents power in a DC circuit with a resistance of 20 ohms, P is the power (in Watts), and I (in amps) is the current.
(Note: This relationship is of the same form as many of the quadratics you will see in this chapter in particular y=x^2(20). As a result the methods you use to solve similar quadratics would apply here.)
If the power is 168.2 Watts what is the current?
