Download Solution PDFCONCEPT:
- Capacitance: The capacitance tells that for a given voltage how much charge the device can store.
Q = CV
where Q is the charge in the capacitor, V is the voltage across the capacitor and C is the capacitance of it.
- When the capacitor is charged with the battery, conservation of energy can be applied here.
- Conservation of energy tells that if the potential energy of the battery decreases the energy of another part of the system must increase by the same amount.
- So, the energy from the battery is stored in the electric field between the plates.
- If no electric field existed between the plates, no energy would be stored between them.
EXPLANATION:
- A capacitor is a device used to store energy for a given voltage.
- When a battery is connected to the capacitor, the energy from the battery is stored in the capacitor.
- This energy is stored in the electric field between the plates.
- So the correct answer is option 4.
