Homework Statement
Three conducting plates, each of area A = 3.5 cm2, are connected in such a way that the center plate can be moved between the two fixed outer plates. If the distances between the outer plates and the center plate are d1 = 0.35 mm and d2 = 0.65 mm, find the effective capacitance C of the system.
Homework Equations
C = E0*A/d
The Attempt at a Solution
I have tried adding the Capacitance of each plate (using equation above) with d1 and then d2 and finally d3 (total distance). I added that together but can't seem to get the right answer. I think it confuses me that there are 3 parallel plates because all the examples we talked about in class have been with 2 parallel plates.
