Capacitance formulas


Capacitance [C] is measured in farads (F)

The unit of measure of charge [Q] is coulomb (C)

The unit of measurement for voltage [U] is the volt (V)



\(\displaystyle capacitance =\frac{charge}{voltage}\)
\(\displaystyle C= \frac{Q}{U}\)

\(\displaystyle U= \frac{Q}{C}\)

\(\displaystyle Q=U·C\)
