1. The problem statement, all variables and given/known data 2. The switch in the circuit below had been closed for a long time before it was opened at t = 0. Given that Vs = 10 V, R1 = 20 kΩ, R2 = 100 kΩ, C1 = 6 μF, and C2 = 12 μF, determine i(t) for t ≥ 0. 2. Relevant equations 3. The attempt at a solution For this problem, my initial thought is that the voltage must be the same across C1 and C2, since they are open, no current runs through R1 nor R2, so the voltage across both is 10 V. Then, I use the equation for the voltage as a function of time, and get the expression. I then take the derivative and multiply by the equivalent capacitance to get my expression. I got a negative answer, I'm not sure if this is right. It would mean the current is the opposite direction that I labeled. Would the current go from the larger capacitor to the smaller one?
