Two capacitor of capacitances 3muF and 6...

Two capacitor of capacitances `3muF and 6muF` are charged to a potential of 12 V each. They are now connected such that the positve plate of one capacitor is connected to the negative plate of the other capacitor. At steady state, the potential difference across the `3muF` capacitor is ______V.

Text Solution

Verified by Experts

The correct Answer is:
4
stored in capacitor `3 mu F = 36 muC `
charge stored on capacitor `6 mu F = 72 mu C `
` V= (Q_("net"))/(C_1 +C_2) `
`V= ( 72 -36 )/( 3+6 ) =4 ` volt
