Question 960410: Solving & Graphing Quadratic Equation
School of electronics
P=i^2(20) represent power in 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 quadratic you will see in this chapter; in particular y=x^2(20). As a result the methods you use to solve similar quadratic would apply here.) if the power is 168.2 Watts, what is the current?
