How to solve the Electric Field in between two parallel charged plates?
What if the charges of the two plates are different?
What if this is the case:
| o | |
Where the | is a plate, and the o is where the electric field is measured. So there would be three plates.
o | | |
or this:
| | | o

Thanks whoever gets this right first automatically gets best answer!
The electric field density of each of the plates are given.

2. Electric field is voltage over distance, and with parallel plates (excluding fringe effects), it's easy; just divide the potential by the distance between the plates. The field is uniform between the inner surfaces.

If you need the displacement field, remember that

D = ?E

3. Charges can't be different

The extra plates do nothing to change the field, assuming the are connected together.

With all of the plates on one side, the field outside the capacitor is due to fringing effects and is very complicated to calculate.
