## Homework Statement

The switch in the following circuit has been opened for a very long time and then closes at t=0 (a) Calculate Vc(t) for t>0. (b) Calculate i(t) for t>0.

## Homework Equations

## The Attempt at a Solution

Here is my attempt of the problem. I have not dealt with a problem that has two voltage sources before. Also, I have not dealt with a problem that does not become source free after the switch is either opened or closed. I am not sure if I am on the right track, I have getting Vc for t<0 to be 24V, however, Vc for t>0 is 36V?... I thought the Vc for both t>0 and t<0 stays the same. Any tips and help is greatly appreciated.
