If the distance between the plates of a parallel plate capacitor is increased by maintain the constant charge on the capacitor, then the energy density between the plates will:
- a)Increase
- b)Decrease
- c)Remain unchanged
- d)Can't say
Correct answer is option 'C'. Can you explain this answer?

CONCEPT:
Capacitor:
- The capacitor is a device in which electrical energy can be stored.
- In a capacitor two conducting plates are connected parallel to each other and carrying charges of equal magnitudes and opposite sign and separated by an insulating medium.
- The space between the two plates can either be a vacuum or an electric insulator such as glass, paper, air, or semi-conductor called a dielectric.
Parallel plate capacitor:
- A parallel plate capacitor consists of two large plane parallel conducting plates separated by a small distance.
- The space between the two plates can either be a vacuum or an electric insulator such as glass, paper, air, or semi-conductor called a dielectric.
The energy stored in the capacitor is given as,
Energy density:
- It is defined as the energy stored per unit volume of space between the plates.
- Energy density u between the plates is given as,
Where C = capacitance of the capacitor, Q = charge on the plates, V = potential difference between the plates, and E = electric field intensity between the plates
EXPLANATION:
- Energy density u between the plates is given as,
- From the above equation, it is clear that the energy density of the parallel plate capacitors does not depend upon the distance between the plates of a parallel plate capacitor.
- Therefore, if the distance between the plates of a parallel plate capacitor is increased by maintaining the constant charge on the capacitor, then the energy density between the plates will remain the same. Hence, option 3 is correct.
