Capacitors in Series

📊 beginner

$$\frac{1}{C_{eq}} = \sum \frac{1}{C_i}$$

Calculates the total capacitance of multiple capacitors connected in a single path.

Variables & Units

$C_{eq}$

Equivalent Capacitance

Unit: Farad ($F$)

$C_i$

Individual Capacitances

Unit: Farad ($F$)

Key Information

📐 Derived From

Charge conservation and voltage addition in series.

💡 Example

Two $10 \mu F$ capacitors in series have $C_{eq} = 5 \mu F$.

🔧 Applications

Voltage dividers and high-voltage filtering.

⚠️ Constraints

Same charge must reside on all capacitors.
