The voltage,V,(in volts)across a circuit is given by Ohm's law:V=IR,where I is the current and R is the resistance(in ohms)If we place three circuits,with resistance R1,R2,R3in parallel,then their combined resistance,R,is given by R/1=R1/1+R2/1+R3/1.suppose that R1 is 1 ohm and increasing a 0.1 ohm/sec and R2is 2 ohms and decreasing at o.2 ohms/sec and R3 is 3 ohms and decreasing at o.3 ohms/sec and the current is 4 amps and increasing at 0.4amps/sec.Find the rate at which the voltage is changing over time.

电压，五， （在伏）的电路是由欧姆定律：钒=红外光谱，在那里我是当前和R是电阻（在欧姆）如果我们把三个电路，与电阻R1 ， R2的R3in并行，那么他们联合抵制，俄，给出的R / 1 = R1 / 1 + R2的/ 1 + R3/1.suppose的R1是1欧姆，增加了0.1欧姆/秒和R2is 2欧姆和减少在o.2欧姆/秒和R3的是3欧姆和减少在o.3欧姆/秒，目前是四安培和增加0.4amps/sec.Find的速度的电压是随着时间的推移不断变化。
