The power in an electrical system varies jointly with the current in the square of the resistance. The power is 200 W one credit is 4 amps and resistance is 5 ohms. 1. write the variation equation describing the relationship between the power (p), current (c), and resistance (r). 2. find the constant of variation or proportionality. 3. find the power when the current is 5 amps and the resistance is 6 ohms.
