In a parallel plate capacitor with air between the plates each plate has an area of 5 × 10-3 metre square and the separation between the plates is 2.5 millimetres. Calculate the capacitance of the capacitor . If this capacitor is connected to 100 volt supply what would be the charge on each plate. How would the charge on the plate be affected if a 2.5 mm thick mica sheet of K equal to 8 is inserted between the plates while the voltage supply remains connected ?
