The voltage, v (in volts), across a circuit is given by ohm's law: v=ir, where i is the current (in amps) flowing through the circuit and r is the resistance (in ohms). if we place two circuits, with resistance r1 and r2, in parallel, then their combined resistance, r, is given by 1r=1r1+1r2. suppose the current is 3 amps and increasing at 0.02 amps/sec and r1 is 4 ohms and increasing at 0.4 ohms/sec, while r2 is 3 ohms and decreasing at 0.2 ohms/sec. calculate the rate at which the voltage is changing.
