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 signs 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 a semi-conductor called a dielectric.
Capacitance:
- The property to store energy in form of charge is called capacitance.
- The unit of capacitance is Farad.
- The charge on the capacitor (Q) is directly proportional to the potential difference (V) between the plates,
⇒ Q ∝ V
⇒ Q = CV
Where C = capacitance
Energy stored in the capacitor:
⇒ Q = CV
Where C = capacitance
Energy stored in the capacitor:
- If a capacitor of capacitance C is charged by a potential difference V, then the energy stored in the capacitor is given as,
CALCULATION:
Given VA = 120 V, VB = 100 V, and UA = UB
Given VA = 120 V, VB = 100 V, and UA = UB
- We know that if a capacitor of capacitance C is charged by a potential difference V, then the energy stored in the capacitor is given as,
By equation 1 for the capacitor A,
By equation 1 for the capacitor B,
By equation 2 and equation 3,
Hence option 2 is correct.
