ファラド

定義

SIの静電容量の単位で、1ボルトの電位差を加えたときに1クーロンの電荷を蓄えるコンデンサの容量として定義される(1 F = 1 C/V)。

解説

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.
