A simple electrical circuit consists of a resistor connected between the terminals of a battery. The voltage V  (in volts) is dropping as the battery wears out. At the same time, the resistance R (in ohms) is increasing as the resistor heats up. The power P (in watts)  dissipated by the circuit is given by P = . Use the equation
= +
to find how much the power is changing at the instant when R = 2 ohms, V = 2 volts, and dV/dt = -0.04 volts/sec.
