What should be the capacitance of a capacitor capable of storing 1j of energy when potential difference of 100V is applied between the plates?

What should be the capacitance of a capacitor capable of storing one joule of energy, when used with a 100 V d.c. supply?

Derive a relation for the capacitance of a parallel plate capacitor having plate separation d, when a dielectric slab of thickness t is placed between the plates.

A parallel plate air capacitor is charged to a potential difference of V volts. After disconnecting the charging battery the distance between the plates of the capacitor is increased using an isulating handle. As a result the potential difference between the plates

How much work must be done to charge a 24 uF capacitor, when the potential difference between the plates is 500 V?

A parallel capacitor has capacitance 20muF . A potential difference of 220 V is applied across it. Calculate the charge on the plates and energy stored in the capacitor. If a dieletric slab of dielectric constant 5 is introduced between its plates, calculate the new value of potential difference and the energy stored.
