Solve the problem.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 = src="https://sciemce.com/media/4/ppg__ttttt0613191120__f1q4g5.jpg" style="vertical-align: -17.0px;" /> 
. Use the equation
= 
+ 
to find how much the power is changing at the instant when R = 4 ohms, V = 2 volts, 
and dV/dt = -0.08 volts/sec.
