Capacitor in Series Calculator

Capacitors connected in series divide voltage and reduce total capacitance. The total capacitance in series is calculated by taking the reciprocal of the sum of the reciprocals of each capacitor's value. This configuration is commonly used in electronic circuits where a smaller equivalent capacitance is needed or when capacitors need to share a voltage load. The Series Capacitor Calculator instantly computes the total capacitance, making it easy to design accurate and efficient circuits for timing, filtering, or energy storage applications.

Formula & Summary

1 / Ctotal = 1 / C1 + 1 / C2 + 1 / C3 + … + 1 / Cn
      
  • Ctotal = Total capacitance (in Farads)
  • C1, C2, ..., Cn = Individual capacitor values

Calculate Series Capacitor

A series capacitor calculator helps determine the total capacitance when multiple capacitors are connected end-to-end (in series). In a series connection, the reciprocal of the total capacitance is the sum of the reciprocals of the individual capacitors. This means that the total capacitance in series is always less than the smallest individual capacitor in the group. Series configurations are often used in high-voltage applications to distribute voltage across each capacitor and to fine-tune capacitance levels. This tool is essential for electronics hobbyists, engineers, and students who need accurate and quick results when designing or analyzing circuits. With this calculator, you can input up to any number of capacitor values and instantly get the total series capacitance in farads, microfarads, nanofarads, or picofarads. It simplifies complex calculations and ensures precision in circuit behavior, especially in timing and filtering applications.

series Capacitor Calculator Data Table

Capacitor (μF) 4.7 10 22
Total Capacitance (μF) 2.75

Calculation:
1/Ctotal = 1/4.7 + 1/10 + 1/22 = 0.2127 + 0.1 + 0.0455 = 0.3582

Ctotal = 1 / 0.3582 ≈ 2.75 μF
