Unit GF
Name gigafarad
Category Capacitance
Details A gigafarad (GF) is a unit of capacitance in the International System of Units (SI). Capacitance is the measure of a capacitor's ability to store electrical charge. It is the ratio of the change in electric charge stored in the capacitor to the resulting change in voltage across the capacitor.

A farad (F) is the standard unit of capacitance, and a gigafarad is equal to one billion (10^9) farads. In other words, if a capacitor has a capacitance of 1 GF, it means that for every one-volt increase in voltage across the capacitor terminals, it can store a charge of one billion (1,000,000,000) coulombs.

In practice, such large capacitance values are rarely used. Capacitors generally have capacitance values in picofarads (pF), nanofarads (nF), or microfarads (µF) due to the typical requirements of electronic circuits. However, gigafarads as a unit illustrate the important physical property of capacitance in storing electrical energy within electrical systems.
