What is series connection of capacitors? And what is parallel connection of capacitors?

(N/A) $1$. Series Connection: Capacitors are connected in series when they are joined end-to-end such that the same charge $Q$ flows through each capacitor. The equivalent capacitance $C_s$ is given by $\frac{1}{C_s} = \frac{1}{C_1} + \frac{1}{C_2} + \dots + \frac{1}{C_n}$. In this arrangement,the total potential difference $V$ is the sum of individual potential drops: $V = V_1 + V_2 + \dots + V_n$.
$2$. Parallel Connection: Capacitors are connected in parallel when all their positive plates are connected to one common terminal and all negative plates to another. In this case,the potential difference $V$ across each capacitor is the same. The equivalent capacitance $C_p$ is the sum of individual capacitances: $C_p = C_1 + C_2 + \dots + C_n$. The total charge $Q$ is the sum of charges on each capacitor: $Q = Q_1 + Q_2 + \dots + Q_n$.
