An empty parallel plate capacitor is connected to a battery that maintains a constant potential difference between the plates. With the battery connected, a dielectric is then inserted between the plates. Does the energy stored by the capacitor increase, decrease or remain the same when the dielectric is inserted?
| remain the same |
| decrease |
| increase |
Homework Answers
Capacitance of capacitor increases when dielectric increase hence more charge can be stored with same potential difference and hence energy will increase as energy E =1/2× q×V.
