The electric power varies directly as the square of the voltage (V) and inversely as the electrical resistance (R). If the voltage is 15 volts and the electrical resistance is 5 ohms, then the electric power is 45 watts. Express the electric power as a function of voltage and electrical resistance. Answer P(V, R) = Keypad Keyboard Shortcut
