The voltage V in 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 = 321, 0.03 A, dv/dt = -0.07 V/s, and dR/dt = 0.02 /s. (Round your answer to six decimal places.) A/S
