We can specify capacitance as the ratio of the change in an electrical charge in a system to the corresponding readjust in its electrical potential.

You are watching: What is the si unit of capacitance

The unit of capacitance is noted in this write-up in a thorough manner so the learners have the right to understand the ide easily.

Usually, there are two forms of capacitance specific self and mutual capacitance. We have covered the object of capacitor and also capacitance in our previous article which you have the right to go through. However, in this page, we will learn around the measure up units.

SI Unit of Capacitance

The SI unit of electric capacitance is Farad i beg your pardon is stood for by the symbol F. The unit is mainly named after ~ English physicist Michael Faraday. Farad is additionally defined together the capability of an object or human body to keep an electrical charge. The is stood for in terms of SI base units prefer s4⋅A2⋅m-2⋅kg-1. That can additional be to express as:

*

Where,

F is FaradV is VoltA is AmpereJ is JouleC is CoulombN is Newtonm is MetreW is watt is Secondkg is KilogramHz is HertzΩ is OhmH is Henry

While the simple unit that capacitance is farad, but this unit is in reality too huge for any practical work. To make points easier, the capacitance is additionally measured in microfarads abbreviated as μF or mfd and also picofarads abbreviated together pF.

Other Capacitance Units

There are assorted other systems of capacitance. Some of the other units are detailed below.

Abfarad (abbreviated abF) i m sorry is an obsolete CGS unit of capacitance same to 109 farads (1 gigafarad, GF).Another rarely used CGS unit is statfarad (abbreviated statF) and it is identical to the capacitance that a capacitor v a fee of 1 statcoulomb across a potential difference of 1 statvolt. In state or farad, the is 1/(10−5c2) i beg your pardon is about 1.1126 picofarads.
