Question

Transcribed Image Text:1. When an air capacitor with a capacitance of 400 nF (1 nF = 10-9) is connected to a power supply,
the energy stored in the capacitor is 3x10-5J. While the capacitor is kept connected to the power
supply, a slab of dielectric is inserted that completely fills the space between the plates. This
increases the stored energy by 2.42×10-5J.
a) What is the potential difference between the capacitor plates before the insertion of the
dielectric?
b) What is the potential difference between the capacitor plates after the insertion of the
dielectric?
c)
d)
What is the dielectric constant of the slab?
If the capacitor is disconnected from the power supply after the charging (the circuit is open),
then you insert the dielectric, what is the potential difference between the capacitor plates
after the insertion of the dielectric?
e) If the capacitor is disconnected from the power supply after the charging (the circuit is open),
then you insert the dielectric, what is the stored energy difference between the capacitor
plates after the insertion of the dielectric?
