The voltage V (volts), current I (amperes), and resistence R (ohms) of an electric circuit are related by the equation V=IR.
Suppose that V is increasing at a rate of 3 volt/sec while I is decreasing at a rate of 1/8 amp/sec. Let t denote time in seconds.
Determine the rate at which R is changing when V = 9 volts and I = 2 amperes.
Answer = _________ ohms/sec
