Total Capacitance vs Capacitor 1
公式
## Series Capacitance Capacitors in series have reciprocal addition, opposite to resistors. ### Formula **1/C_total = 1/C1 + 1/C2 + ...** The total capacitance is always less than the smallest individual capacitor. This is the opposite behavior from resistors in series.
计算示例
Two capacitors in series: 100 μF and 220 μF.
- 011/C = 1/100 + 1/220 = 0.01 + 0.004545 = 0.014545
- 02C = 1 / 0.014545 = 68.75 μF
常见问题
Why does series capacitance decrease?
In series, the same charge appears on each capacitor but the voltages add. Higher total voltage for the same charge means lower effective capacitance.
When would you put capacitors in series?
To achieve a lower capacitance than available or to increase the voltage rating (each capacitor only sees part of the total voltage).
Is the formula the same as parallel resistance?
Yes, the reciprocal addition formula is identical. Capacitors in series combine like resistors in parallel.
