#Equivalent Capacitance

#Capacitor Combinations 🔌

• Capacitors in circuits can be simplified into a single equivalent capacitance ($C_{eq}$). This helps in analyzing complex circuits.

• Series Capacitors:

  • The reciprocal of the equivalent capacitance is the sum of the reciprocals of individual capacitances: $$\frac{1}{C_{\text{eq, s}}} = \sum_{i} \frac{1}{C_i}$$

• Parallel Capacitors:

  • The equivalent capacitance is the sum of individual capacitances: $$C_{\text{eq, p}} = \sum_{i} C_i$$
