Question

Derive an expression for net capacitance of three capacitors in series combination

Answer 1

Answer:

Explanation:

Let  the three capacitors are c1,c2and c3

we know that,  Q = CV

                        V = Q/C

Now, net capacitance of three capacitors in series combination

         

             V = v1 + v2+ v3

            Q/C = Q/c1 + Q/c2 +Q/c3     {Q is constan in series combination of

            1/C = 1/c1 + 1/c2 + 1/c3              capacitors}
