1 Capacitance
Two capacitors C1 and C2 are charged to 120 V and 200 V respectively. It is found that by connecting them together the potential on each one can be made zero. Then
1) 5C1 = 3C2 2) 3C1 = 5C2 3) 3C1 + 5C2 = 0 4) 9C1 = 4C2
Potential = 0 on connecting them together i.e. Q = 0 i.e. C1V1 = C2V2 [capacitance is positive but they are connected with opposite polarity] 120 C1 = 200 C2 3C1 = 5C2
