The voltage, V (in volts), across a circuit is given by Ohm's law: V = IR, where I is the current (in amps) Howing 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 1 1 1 R R1 R2 Suppose the current is 3 amps and increasing at 0.02 amps/sec and R1 is 4 ohms and increasing at 0.5 phms/sec, while R, is 3 ohms and decreasing at 0.3 ohms/sec. Calculate the rate at which the voltage is changing. volts/sec Submit answer

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
