Capacitance Calculator

Find capacitance from stored charge and voltage.

Capacitance (F) 0

Capacitance (µF) 20

Formula: C = Q ÷ V

Step-by-step with your numbers:

1. Values used:

2. Charge = 0.0001 C

3. Voltage = 5 V

5. Capacitance = Charge / Voltage = 0.0001 / 5 = 0F

6. Capacitance = 20µF

Did we solve your problem today?

Capacitance measures how much charge a component stores per volt.

The math behind it

C = Q ÷ V. One farad stores one coulomb per volt.

100 µC at 5 V → 20 µF.

Why are farads usually tiny?

A farad is huge; real capacitors are typically pico- to micro-farads.
