2.9) Explain what would happen if in the capacitor given in exercise 2.8, a 3 mm thick mica sheet (of dielectric constant = 6) were inserted between the plates, (a) while the voltage supply remained connected.
Dielectric constant of the inserted mica sheet = 6
Thickness of the sheet = 3mm
Initial Capacitance =
Final Capacitance =
Final Charge on the capacitor =
Hence on inserting the sheet charge on each plate changes to .
