Frequently asked questions
How do you add capacitances in parallel?
Add them directly: C = C₁ + C₂ + ...
How are they calculated in series?
1/C = 1/C₁ + 1/C₂ + ...
Is the formula the same as for resistors?
The series and parallel rules are the reverse of those for resistors.
What unit does the tool use?
Microfarads, µF.
