# How to force like charges on opposing plates ?

Hello !

What would be the circuit to have opposing plates charged with the same charges ?

Is it even possible to do it with an eletric circuit ?

Have a nice day

You could charge each plate separately with a plus voltage to a ground plate.
Then disconnect the voltage, leaving the plates charged, and then move them close to each other.

Or, short the plates together. If you want to describe that as a high or low charge would then depend on the reference.

So what's the purpose of doing this?

The charge is not stored on the plates, it is stored in the dielectric (insulation) between the plates.

@ErnieM 's post #5 almost does it, if you want to charge the plates with respect to earth.

I don't think your question can be answered unless you specify to what the charges on the plates is relative.

Hi ,
That would be used in dielectric elastomers

Yeah I forgot to add that the plates are charged relative to earth
