Frequently asked questions
Multiply capacitance by voltage: Q = C × V. A 1 mF capacitor at 12 V holds 0.012 coulombs.
It is the unit of capacitance: one farad stores one coulomb per volt.
Charge is C × V; stored energy is ½ × C × V², which depends on voltage squared.
Charge rises directly with voltage, so a higher voltage stores more charge on the same capacitor.
