In a simple electric circuit, Ohm’s law states that V=IR, where V is the voltage in volts, I is the current in amperes, and R is the resistance in ohms. Assume that, as the battery wears out, the voltage decreases at 0.01 volts per second, and as the resistor heats up, the resistance is increasing at 0.02 ohms per second. When the resistance is 200 ohms and the current is 0.03 amperes, at what rate is the current changing?
