Question
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: 1/R = (1/R1)+(1/R2) Supposed the current is 3 amps and increasing at 10^-2 amp/sec and R1 is 5 ohms and increasing at 0.5 ohm/sec, while R2 is 12 ohms and decreasing at 0.1 ohm/sec. Calculate the rate at which the voltage is changing. Rate = ? volts/sec Show all steps and round the answer to three decimal places.Explanation / Answer
15/8.10^-2+2*25/64 (-0.5)+2*9/64(-0.1)
=-0.4 volts/sec
