Two capacitors C_(1) and C_(2) are charged to same potential V, but with opposite polarity as shown in the figure. The switches S_(1) and S_(2) are then closed

Answer»

Potential difference across TWO capacitors are same and is GIVEN by`((C_1 - C_(2)) V)/(C_(1) + C_(2))`
Potential difference across two capacitors are same and is given by `((C_(1) + C_(2))/(C_(1) - C_(2)))V`
Ratio of final energy to initial energy of the system is given by `((C_(1) - C_(2))^(2))/(C_(1) + C_(2))^(2)`
Ratio of final energy to initial energy of the system is given by `((C_(1))^(2))/((C_(1) + C_(2))^(2))`
