via: Ohm's Law states that across a resistor, the voltage of, resistance of, and current through the resistor are related V = IR where V is given in volts, I is given in amps, and R is in ohms. Assume at time t = 5 that I = .5A and R= 200. If at time t = 5, I is decreasing at a rate of .3Amp/s, and the resistance at any given time is governed by the equation R(t) = e-5t, find the rate of change of the voltage.
