Three resistors are connected in series to a 95.6 V battery: R1 = 3.39 Q, R2 = 9.19 N and R3 = 3.96 N. Now, as R3 heats up, its resistance increases according to: dR3 = 0.366 N/s dt dP Assume the resistance of the other resistors remain constant. Find dt , the rate at which the power pulled from the battery is changing in W/s, at the instant R3 = 16 N. The sign shows whether the power is increasing or decreasing.
