1. The problem statement, all variables and given/known data find the equvialent capacitace 2. Relevant equations ceq=c1+c2 1/ceq=1/c1+1/c2 3. The attempt at a solution I know how to do some of these problems but this one has me stumped. I don't know how to start since the middle capacitor screws everything up. I think my teacher did it but I wasn't there for it and he won't do it again. Any help would be appreciated greatly. Don't worry about the charges and other specs as I can deal with that easily. Just the problem of the middle capacitor. I don't even know where to start to attempt this.
