A network of four capacitors of capacity equal to C1=C,C2=2C,C3=3C and C4=4C are connected to a battery as shown in the figure. The ratio of the charges on C2 and C4 is:
Open in App
Solution
Capacitor C1,C2,C3 are in series
Resultant capacitance 1Cs=1C+12C+13C
∴Cs=6C11
For capacitors in series charge on each one each capacitor is equal
