Question

2 capacitors of capacitances 6 microfarad and 3 microfarad are charged to 12 volts and 6 volts respectively. now they are connected in parallel. find the common potential difference and the charge on each capacitor after connection​

Answer 1

Answer:

C

1

=3μF

C

2

=6μF

V=12V each

∴Q=CV

Q

1

=36μF

Q

2

=72μF

After positive and negative plates of both capacitors joined together. then,

Q

net

=36μC(72−36μF)

and C

net

=(3+6)μF

∴ or V=

C

Q

V=

9μF

36μC

or V=4V
