An electric toaster operating on 120 volts draws a current of 53 amperes. The resistance of the toaster is?   Calculate to 1 decimal

The Voltage V in volts , the resistance R in ohms , and the current I in amperes in an electric circuit are related by the formula V = R I. The resistance in an electrical circuit is decreasing at the rate of 4 ohms / s, while the voltage remains constant at 12 volts. At what rate is the current changing at the instant the current is 6 amperes? The current is decreasing at the rate of 12 amperes / s The current is decreasing at the rate of 18 amperes / s The current is increasing at the rate of 18 amperes / s The current is increasing at the rate of 12 amperes / s The current is decreasing at the rate of 3 amperes / s O The current is increasing at the rate of 3 amperes / s
