Series: Charge is the same on each capacitor. Parallel: Total charge is the sum of charges on each capacitor.

Series: Reciprocal addition is used. Parallel: Capacitances are added directly.

Initially: Current flows freely. Steady State: No current flows; acts as an open circuit.

Charging: Current decreases exponentially. Discharging: Current (magnitude) decreases exponentially, and flows in the opposite direction.

Series: Voltage is split across capacitors. Parallel: Voltage is the same across each capacitor.

Series: Charge is the same on each capacitor ($Q_{total} = Q_1 = Q_2 = Q_3 = ...$) | Parallel: Total charge is the sum of charges on each capacitor ($Q_{total} = Q_1 + Q_2 + Q_3 + ...$)

Series: $\frac{1}{C_{total}} = \frac{1}{C_1} + \frac{1}{C_2} + \frac{1}{C_3} + ...$ | Parallel: $C_{total} = C_1 + C_2 + C_3 + ...$

Initial State: Current flows freely, capacitor is uncharged | Steady State: No current flows, capacitor is fully charged and acts as an open circuit.

Series: Voltage is split across each capacitor. | Parallel: Voltage is the same across each capacitor.

Series: Current is the same through each capacitor. | Parallel: Current divides through each capacitor.
