Units of Electric current

Units of electric charge

The S.I. unit of charge is Coulomb represented by ‘C’.

And this is the amount of charge that is contained by 6 X  1018 electrons

Charge on 1 electron =  -1.6 X 10-19 C

Charge on 1 proton = +1.6 X 10-19 C

  • Electric current

To understand this concept in an easy way lets read the following rhyme:-

Flow of Air

Makes  air current,

Flow of water

Makes water currents


Flow of electric charges

Make electric current.

Finally electric current is the amount of charge flowing through a particular area in a unit time.

Or simply it is the rate of flow of the electric charges.

It is represented by I

Electric current = charge/time

I = Q/t
