Capacitance vs Charge
Formula
## Capacitance Capacitance measures the ability of a component to store electric charge per unit voltage. ### Formula **C = Q / V** where Q is the stored charge in coulombs and V is the voltage across the capacitor. The unit is the farad (F).
Exemplo Resolvido
A capacitor stores 0.001 C of charge at 5 V.
- 01C = Q / V
- 02C = 0.001 / 5
- 03C = 0.0002 F = 200 μF
Perguntas Frequentes
What is a farad?
One farad is the capacitance that stores one coulomb of charge per volt. In practice, most capacitors are measured in microfarads (μF) or picofarads (pF).
What determines the capacitance of a parallel plate capacitor?
C = epsilon * A / d, where epsilon is the permittivity of the dielectric, A is the plate area, and d is the plate separation.
What is a supercapacitor?
A supercapacitor can store thousands of farads by using extremely thin dielectric layers and large surface areas. They bridge the gap between capacitors and batteries.
