Three resistors are connected in parallel to a 69.5 V battery: R1 = 8.18 N, R2 = 8.01 N and R3 = 6.63 Q. Now, as R3 heats up, its resistance increases according to: %3D dR3 = 0.301 Q/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 = 29 Q. The sign shows whether the power is increasing or decreasing. How does the rate at which the power changes in a parallel circuit with the rate the power changes in a series circuit?
