Question

An initially uncharged air-filled capacitor is connected to a 2.53-V charging source. As a result, 4.87 times 105 C of charge is transfered from one of the capacitor's plates to the other. Then, while the capacitor remains connected to the charging source, a sheet of dielectric material is inserted between its plates, completely filling the space The dielectric constant of this substance is 4 07. Find the capacitor's potential difference and charge after the insertion. Potential difference after insertion of dielectric: Charge after insertion of dielectric:

Explanation / Answer

Potential difference= 2.53 V( remain same)

Q=KQo=1.9821*10^-4 C
