the capacitor will act like a short, and the circuit would look like only R3 and R2 in parallel, with the rest of the loop intact. if we look back at part 1 of the question, the current in I4 was found at t=0. so would that current apply here? same current passes through R1 and the simplified R23 set since it's all in series now. correct? what's next then?gneill said:If you're looking for Ic's maximum value, that occurs the instant the switch is closed and the capacitor is completely uncharged. How does an uncharged capacitor behave (what does it "look like" to the rest of the circuit)?
right, the maximum current would be at t=0, so the exponential equals 1. slipped my mind. solved itWhat are you looking to determine? Why is a time value required?
