Two capacitors of 10 PF and 20 PF are connected to 200 V and 100 V sources respectively. If they are connected by the wire, what is the common potential of the capacitors ?

133.3 volt

150 volt

300 volt

400 volt

Text Solution

Verified by Experts

The correct Answer is:

`V = (C_(1)V_(1) + C_(2)V_(2))/(C_(1) + C_(2)) = (10 xx 200 + 20 xx 100)/(10 + 20) = 133.33 V`
