Question -

A 600 pF capacitor is charged by a 200 Vsupply. It is then disconnected from the supply and is connected to anotheruncharged 600 pF capacitor. How much electrostatic energy is lost in theprocess?



Answer -

Capacitance of the capacitor,┬аC┬а=600 pF

Potential difference,┬аV┬а=200 V

Electrostatic energy stored in the capacitor is given by,

If supply is disconnected from thecapacitor and another capacitor of capacitance┬аC┬а= 600 pF isconnected to it, then equivalent capacitance (CтАЩ) of thecombination is given by,

New electrostatic energy can be calculated as

Therefore, theelectrostatic energy lost in the process is
