abfarads
n. countable C2 Proficiency ab·farads
n. a very large unit used to measure the ability of a material to store electricity. It is much bigger than the farad, which is the standard unit.
n. a unit of electrical capacitance equal to one billion farads. It is the CGS (centimetre-gram-second) unit of capacitance and is rarely used in modern engineering contexts.
The capacitor had a value of one abfarad.
In historical physics textbooks, you might find capacitance values listed in abfarads rather than the more common farads.
While the farad is the standard SI unit for capacitance, the abfarad remains a theoretical reference point in certain classical electromagnetism equations.
