47. Changing voltage in a circuit The voltage V in a circuit that satisfies the law V = IR is slowly dropping as the battery wears out. At the same time, the resistance R is increasing as the resistor heats up. Use the equation aV dR dV _ aV dI al dt dt ƏR dt to find how the current is changing at the instant when R = 600 ohms, I = 0.04 amp, dR/dt = 0.5 ohm/sec, and dV/dt = -0.01 volt/sec. Battery
