Question

A parallel plate capacitor is charged to voltage V and then disconnected from the battery. Leopold says that the voltage will decrease if the plates are pulled apart. Gerhardt says that the voltage will remain the same. Which one, if either, is correct, and why?

Answer 1

Both Leopold and Gerhardt are wrong

Step-by-step explanation:

The voltage is equal:

`V=(Q)/(C) =(Qd)/(\epsilon _(o)A )`

If the plates are separated, the voltage will increase, therefore they are both wrong.
