1 pts Question 1 A parallel plate capacitor with plates of area A and plate separation d is charged so that the potential difference between its plates is V. If the capacitor is then isolated and its plate separation is decreased to d2, what happens to the potential difference between the plates? The final potential difference is 4V The final potential difference is 2V The final potential difference is 0.5V The final potential difference is 0.25V The final potential difference is V
