Hello everyone! I was able to get parts, a-c of this problem, but i'm confused on what stage i'm suppose to use to find T = RC, let t = time. The problem says: For the cirucit find Vc(t) at t equal to (a) 0-; (b) 0+; (c) infinity; (d) .08s Answers: a: 20v b: 20v c: 28v d: 24.4 Note: that is a unit step fucntion, at time = 0, u have no voltage of 10V, at time t > 0 you will have 10V added to the circuit. so if this is the circuit: I know the equation is going to look like this: Vc(t) = 20*e^-tT; so all i need is T = RC; I need to remove all the power sources and look through the conductor right? but thats the part that confusese me, because the conductor is right in the middle, there is a resistor on both sides, so which side do i "look" from? left or right? Or am i not doing this right at all? THanks!
