Flat dielectric filled capacitor and its plate filed certain potential difference. Its energy is then equal to 2 x 10 -5 J. After the capacitors are disconnected from the voltage source, insulator removed from the condenser. The work had to make against the forces of the electric field to remove the insulator, is 7 × 10 -5 J. Find the permittivity of the dielectric.
Detailed solution with a short recording conditions, laws and formulas used in the decision, the withdrawal of the calculation formula and the answer.
If you have any questions about the decision to write. I try to help.
