Abvolt

The abvolt (abV) is the unit of potential difference in the <a href="/facts/Centimetre%25E2%2580%2593gram%25E2%2580%2593second_system_of_units/qbHxv78q">CGS-EMU system of units</a>. It corresponds to 10−8 volt in the <a href="/facts/SI/NShmfzlD">SI</a> system and 1/ccgs <a href="/facts/Statvolt/pUGTepVY">statvolt</a> ≈ 3.3356×10−11 statvolt in the <a href="/facts/Centimetre%25E2%2580%2593gram%25E2%2580%2593second_system_of_units/qbHxv78q">CGS-ESU system</a>.
A potential difference of 1 abV will drive a current of one <a href="/facts/Abampere/Lq16LXyW">abampere</a> through a resistance of one <a href="/facts/Abohm/TrpxnHKG">abohm</a>.
In most practical applications, the volt and its multiples are preferred. The national standard in the United States deprecates the use of the abvolt, suggesting the use of volts instead.
The name abvolt was introduced by <a href="/facts/Arthur_E._Kennelly/MjkargSj">Kennelly</a> in 1903 as a short name for the long name (absolute) electromagnetic cgs unit of e.m.f. that was in use since the adoption of the cgs system in 1875. The abvolt was <a href="/facts/Coherence_(units_of_measurement)/bg3o7Msc">coherent</a> with the CGS-EMU system, in contrast to the volt, the <a href="/facts/Centimetre%25E2%2580%2593gram%25E2%2580%2593second_system_of_units/qbHxv78q">practical unit</a> of e.m.f. that had been adopted too in 1875.
