What is the potential difference between the capacitorplates

Reference no: EM13558736

When an air capacitor with a capacitance of 400 nF (1nF=10^(-9) F)is connected to a power supply, the energy stored in the capacitoris 2.05×10^(−5) J. While the capacitor is keptconnected to the power supply, a slab of dielectric is inserted that completely fills the space between the plates. This increasesthe stored energy by 2.46×10^(−5) J.

1) What is the potential difference between the capacitorplates?
2) What is the dielectric constant of the slab?
