The plates of a parallel plate capacitor have an area `(20 cm^2)` each are separated by a distance of 2.5 mm. The capacitor is charged by connecting it to a 400V supply. How much electrostatic energy is stored in the capacitor?

The plates of a parallel plate capacitor have area of 90cm^2 each and are separated by 2.5mm. What would be its capacitance? [epslion_0 =8.85 * 10^(-12) C^2N^(-1) m^(-2)]

A 600 pFcapacitor is charged by a 200 V supply. It is then disconnected from the supply and is connected to another uncharged 600 pF capacitor. How much electrostatic energy is lost in the process?

In parallel plate capacitor with air between the plates, each plate has an area of 6 xx 10^3m^2 and the distance between the plates is 3mm. Calculate the capacitance of the capacitor if it is connected to 100V supply.What is the charge on each plate of the capacitor?

What is the area of the plates of a 0.1 µF parallel plate air capacitor, given that the separation between the plates is 0.1 mm.
