Question

Explain the combination of series capacitors . Derive the formula for equivalent capacitance​

Answer 1

Answer:

When several capacitors are connected in a series combination, the reciprocal of the equivalent capacitance is the sum of the reciprocals of the individual capacitances. When several capacitors are connected in a parallel combination, the equivalent capacitance is the sum of the individual capacitances.

Explanation:

We can find an expression for the total (equivalent) capacitance by considering the voltages across the individual capacitors. The potentials across capacitors 1, 2, and 3 are, respectively, V1=Q/C1, V2=Q/C2, and V3=Q/C3.
