Capacitors in Series

Capacitors in Series

$$\frac{1}{C_{eq}}=\frac{1}{C_1}+\frac{1}{C_2}$$ $$\Delta V=\Delta V_1+\Delta V_2$$ $$Q=Q_2=Q_1$$

Capacitors in Parallel

$$C_{eq}=C_1+C_2$$ $$Q=Q_1+Q_2$$ $$\Delta V=\Delta V_1=\Delta V_2$$

General Formulas

$$\Delta V=\frac{Q}{C}$$ $$Q=C_{eq}\Delta V$$

• This is all very similar to V = IR
• Q would replace I, and C would replace R
