Question

Discuss the series combination of capacitor and derive it's formuls?​

Answer 1

In series circuit the charge through each capacitor is  the same let this be Q.

Consider two capacitors of capacitance C1 & C2 let the potential through the capacitor be V1 & V2.

Then

V1=Q/C1

V2=Q/C2

V=Q/Ceq

V=V1+V2

Q/Ceq=Q/C1+Q/C2

⇒1/Ceq=1/C1+1/C2

for n capacitors in series

1/Ceq=1/C1+1/C2+........1/Cn

Answer 2

Series combination of capacitor formula

The formula for calculating the series total capacitance is the same form as for calculating parallel resistances: When capacitors are connected in parallel, the total capacitance is the sum of the individual capacitors' capacitances.
