# When I connect two charged capacitors side by side, what will be the voltage across them?

Say, I have two charged capacitors, one 3mF and one 2mF. The voltage across them are 20V and 30V respectively. Now if I connect the two capacitors side by side as shown below, what will be the voltage across each capacitor?

     open -------||----------------||-----------open
20V, 3mF            30V, 2mF

They are connected in series, so the voltage doesn't change. They should still have 20V and 30V respectively. –  sidht Aug 8 '12 at 5:21

since circuit is open no charge is shared. if the circuit is closed ie capacitors are connected by conducting wire then charge will be shared. charge would flow from higher potential to lower until they come to common potential.

In the given circuit no charge is shared and potential across both the capacitors remains same.
