The voltage Vin a simple electrical circuit is slowly decreasing as the battery wears out. The resistance R is slowly increasing as the resistor heats up. Use Ohm's Law, V = IR, to find how the current I is changing at the moment when R = 456 n, I = 0.05 A, dV/dt = -0.09 V/s, and dR/dt = 0.06 N/s. (Round your answer to six decimal places.) A/s
