A60pFcapacitor is fully charged by a20Vsupply. It is then disconnected from the supply and is connected to another uncharged60pFcapacitor in parallel. The electrostatic energy that is lost in this process by the time the charge is redistributed between them is (innJ) ________

Question diagram: A 60 p F capacitor is fully charged by a 20 V supply. It is
Answer:
6.00
Solution:


V0=20V
Heat loss=Ui-Ut
=12Cvo2-212CV022
=CVo24
=60×10-122024J
=6×10-9J=6 nJ
