Capacitance Calculator — C = Q/V

Capacitance measures how much charge a capacitor holds per volt. Bigger plates and smaller gaps mean more capacitance.

Capacitance Calculator — C = Q/V

C=QVC = \frac{Q}{V}

How to interpret the result

A 100 µF capacitor at 12 V stores 1.2 mC — enough to keep a small circuit alive briefly when power blips.

Assumptions

  • Ideal capacitor (no leakage)
  • DC steady state
