Two Capacitors in Parallel
Enter your known values, leave one input blank, and solves for the missing one. Try different units for next level excitement!
Learning zone
Wired in parallel, both capacitors see the same voltage, and their plate areas effectively pool into one bigger capacitor — so capacitances simply add. A 4.7 µF and a 2.2 µF part side by side behave as 6.9 µF. Designers exploit this to hit odd values, or to pair a big bulk capacitor with a small fast one.

- Total capacitance — RC Time Constant, Capacitance (C = Q/V)
- Capacitance 1 — RC Time Constant, Capacitance (C = Q/V)
- Capacitance 2 — RC Time Constant, Capacitance (C = Q/V)
