TS EAMCET · Physics · Capacitance
A capacitor is fully charged with a battery and then disconnected. A dielectric is then inserted into the capacitor. How do charges on surface of the dielectric and outer surface of the plates of the capacitor would change respectively?
- A Increases, decreases
- B Decreases, increases
- C Increases, remain unchanged
- D Remains unchanged, increases
Answer & Solution
Correct Answer
(C) Increases, remain unchanged
Step-by-step Solution
Detailed explanation
As capacitor is disconnected from battery. Its charges at the plates will get stored in the form of electrostatic energy (Case I). When a dielectric is introduced inside this capacitor, it gets polarised as shown in (Case II). Due to this, charges at surface of dielectric gets…
