Coulomb

From Simple English Wikipedia, the free encyclopedia

The Coulomb (sometimes written C) the SI unit of electric charge. It is named after Charles-Augustin de Coulomb.


[edit] Definition

1 coulomb is the amount of electric charge carried by a current of 1 ampere flowing for 1 second.

1 \ \mathrm{C} = 1 \ \mathrm{A} \cdot 1 \ \mathrm{s}

It can also be defined in terms of capacitance and voltage, where one coulomb is defined as one farad of capacitance times one volt of electric potential difference:

1 \ \mathrm{C} = 1 \ \mathrm{F} \cdot 1 \ \mathrm{V}
