패럿

정의

1 V의 전위차를 인가했을 때 1 C의 전하를 저장하는 축전기의 전기 용량으로 정의되는 SI 전기 용량 단위(1 F = 1 C/V).

설명

Named after Michael Faraday. One farad is an enormous capacitance — most electronic capacitors are measured in microfarads (µF, 10⁻⁶ F), nanofarads (nF), or picofarads (pF, 10⁻¹² F). Supercapacitors used in electric vehicles and energy storage can reach thousands of farads. A 1 F capacitor charged to 1 V stores 0.5 joules of energy.
