1. The problem statement, all variables and given/known data By the time t = 0, the network was in steady state. At time t = 0, the switch is turned on. Find the voltage on the capacitance C2 immediately after the commutation. 2. Relevant equations KCL i(-0) = -ic1(+0) - ic2(+0) KVL E-i(-0) * R-Vc1(-0) = 0 Vc1(+0) = Vc2(+0) 3. The attempt at a solution The picture attached, The current at t = - 0 is i(-0) = E/R+R1, at time t = +0 ,R1 and R2 are both being short circuited by C2,but are my KVL and KCL equations even right?I think I messed up with times +0 and -0. How do I approach commutation in circuits? It's really confusing for me since I've just started learning about it.
