Question:

The voltage V (volts), current I (amperes), and resistance R (ohms) of an electric circuit like the one shown here are related by the equation V = IR. Suppose that V is increasing at the rate of 1 volt/sec while I is decreasing at the rate of 1/3 amp/sec. Let t denote time in seconds.image


a. What is the value of dV/dt?


b. What is the value of dI/dt?


c. What equation relates dR/dt to dV/dt and dI/dt?


d. Find the rate at which R is changing when V = 12 volts and I = 2 amps. Is R increasing, or decreasing?
