What is the SI unit for capacitor?
- farad (f)
- s.i capicitor unit is farad.
well capacitor the charge storage device and its charge storage capacity are measured in ‘farad’ although the farad is a bulky unit, so it is generally measured in milli farad, micro farad, nano farad, etc.
the capacitor is a, somewhat simplified, can be described as having the purpose of storing electrical charges.
Physical devices do not come with units if it does not matter if they are capacitors, cars or cats.
Now, I guess what you want is a number (with unit) that describes a specific capacitor property. the quantity you are looking for would most likely be called capacitance, and is measured in farad.
it is the farad (f) and, as others have underlined, the storage of a coulomb of charge is carried out when a DC voltage is supplied to the terminals.
The problem in electronics is that a farad is very big. you will usually only see electrolytics in terms of milli (mf) and more normally microfarad (uf) and smaller capacitors go to nano and pico (nf, pf). You can also get femto (ff), but they are not easy to find and you only see them in a very specialized job because it is very difficult to stop submerging them. the biggest plug I have in my spare parts is 1000 uf (1 mf) and the smallest, 10 pf (it’s a ceramic disc and it’s tiny).
Thus, although the unit in academic terms is the farad, in the practical work, we would examine the divisions.
