The capacitor was originally known as the condenser, a term still encountered in a few compound names, such as the condenser microphone.
What is a large capacitance of an electrostatic system?
The capacitance (C) of an electrostatic system is the ratio of the quantity of charge separated (Q) to the potential difference applied (V). The SI unit of capacitance is the farad [F], which is equivalent to the coulomb per volt [C/V]. One farad is generally considered a large capacitance. Energy storage Since Q = CV, and also since C = Q/V
How much electrical charge can a capacitor store on its plates?
