Correct answer: B — Farads
Explanation lettering: C = shown as A · E = shown as B · B = shown as C · A = shown as E
Capacitance (the ability to store electrical charge) is measured in Farads (F). C = Q/V where Q = charge (Coulombs) and V = voltage. Capacitance is relevant to defibrillators (which store charge in a capacitor for controlled discharge) / ECG filters / and electrical safety (stray capacitance can cause microshock).
