```										DEAR GOPALAM VANAPALLI,
IN CASE OF PARALLEL COMBINATION OF CAPACITANCES,
Ceq = e0Aeq/d = e0(A1+A2)/d = e0A1/d + e0A2/d = C1 + C2Thus, Ceq = C1 + C2.
WHEREAS IN SERIES COMBINATION ,
The quantity that adds is the voltage across each capacitorDV = DV1 + DV2The voltage across the capacitors is related to their chargeDV1 = Q/C1   and   DV2 = Q/C2The definition of the equivalent capacitance is Ceq = Q/DV, or DV = Q/Ceq. ThereforeQ/Ceq = Q/C1 + Q/C2We can divide out the common factor of Q to arrive at
1/Ceq = 1/C1 + 1/C2
