What is capacitance?
Quick Answer
Capacitance is the ability of a system to store electric charge per unit voltage. It is measured in farads.
The Full Story
A capacitor is the most common device used to provide capacitance. It stores energy in an electric field between two conductors separated by an insulating material. Capacitance is measured in farads, though practical components usually use microfarads, nanofarads, or picofarads because a farad is a very large unit. Capacitors are used in power supplies, cameras, radio tuning circuits, and many electronic devices. They can smooth voltage changes, store short bursts of energy, and help filter signals.
