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 Ris the resistance (in ohms). If we place two circuits, with resistance R1 and R2, in parallel, then their combined resistance, R, is 1 given by R 1 1 .Suppose the current is 5 amps and increasing at 10-2 amp/sec and R1 is 8 ohms and increasing at 0.9 R2 R1 ohm/sec, while R2 is 7 ohms and decreasing at 0.3 ohm/sec. Calculate the rate at which the voltage is changing. Round your answer to three decimal places. i volts/sec

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 Ris the resistance (in ohms). If we place two circuits, with resistance R1 and R2, in parallel, then their combined resistance, R, is 1 given by R 1 1 . Suppose the current is 5 amps and increasing at 102 amp/sec and Rị is 8 ohms and increasing at 0.9 + R1 R2 ohm/sec, while R2 is 7 ohms and decreasing at 0.3 ohm/sec. Calculate the rate at which the voltage is changing. Round your answer to three decimal places. i volts/sec
