Question

if a capacitor is added to a group of capacitor already connected in series , what will be the effect on equivalent capacitor?​

Answer 1

Answer:

The equivalent capacitance of the group will decrease.

Explanation:

When the capacitors are connected in series, the equivalent capacitance is given as,

$C_{eq}=\frac{1}{C}+\frac{1}{C'}$

where, C is the capacitance of the capacitor and C' is the capacitance of group of capacitors.
