A capacitor of `4muF` is connected to 400 V supply. It is then disconnected and connected to an uncharged capacitor of `2muF`. Calculate the comon potential after the capacitors are connected together.

When a capacitor is connected to a battery

A 4 muF capacitor is charged by a 200 V supply. It is then disconnected from the supply, and is connected to another uncharged 2 muF capacitor. How much electrostatic energy of the first capacitor is lost in the form of heat and electromagnetic radiation?

A 10 mu F capacitors is charged by a 30 V d.c supply and then connected across an uncharged 50 mu F capacitor. Calculate (i) the final potential diff. across the combinition

A 600pF capacitor is charged by a 200V 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?

A 10 muF capacitor is charged to a potential difference of 50 V and is connected to another uncharged capacitor in parallel. Now the common potential difference becomes 20 volt. The capacitance of second capacitor.

Calculate the total capacitance of a number of capacitors connected in parallel.

A 5 mu F capacitor is charged fully by a 220 V supply. It is then disconnected from the supply and is connected in series to another uncharged 2.5 mu F capacitor . If the energy change during the charge redistribution is X//100 J Find the value of X to the nearest interger.

A capacitor of 20 muF charged uptp 500 V is connected in parallel with another capacitor of 10 muF which is charged upto 200 V. The common potential is
