Question

what is the main difference between parralel capacitor or series capacitor?​

Answer 1

$\huge{\mathcal{\red{A}\green{N}\pink{S}\orange{W}\blue{E}\pink{R}}}$

When the potential difference across the plates is equal, they are in parallel. When the current through them is equal, they are in series. Here, in circuit A, the capacitors are in series, while in B, they are in parallel. Here, the top circuit represents 3 capacitors in series.

Answer 2

Explanation:

When capacitors are connected in parallel the total capacitance is the sum of the individual capacitors. With resistors series connection results in additive value while parallel connection results in diminished value.
