I am doing a homework problem to solve for the voltage across the capacitor. Our teacher gave us a seven step method to solve for them and told us not to worry about the differential equation way right now.
We have to find the Vc(t) when t < 0 and when t = ∞. I can find Vc(t) when t = ∞ easy enough but when I try to find when t < 0 I am not getting the right answer according to the book.
I try to simplify the circuit down and get a resistance of 4K to the left and then a single resistor to the right of 2k. Once I have that I use voltage division to get the voltage across Vc(t) = 4V but the book is saying its 12V and i am just not sure why or where I am going wrong. Any help or explanation would be appreciated.
