Question

An infinite no of capacitor of capacity c 4c 16c are connected in series then what will be the resulting capacitance

Answer 1

Answer:

3/4 or 0.75 c

Explanation:

Capacitance in series 1/C=1/c1 + 1/c2+......

Here we create a G. P its sum is given by :- a/1-r

Hence we get 1/(1-1/4) = 4/3=1/C

So capacitance= 3/4c

Answer 2

answer

$\frac{c}{2}$
