Expert Answer
Colomb is the derived SI unit of electric charge. it is the quantity of electricity transported in one second by a current of 1 ampere.
The statcoulomb or esu is the physical unit for electrical charges used in the cgs units. It is a derived unit given by
- 1 statcoulomb or esu = 0.1 A m / c ; where c is the speed of light.
This works out to be:
1 esu = 0.1 (C/s) * m / (299,792 m/s)
or 1 esu = 3.334564 x 10-10 C - or 1 C = 3.00×109 statC or esu,
- Whie absolute coulomb defined as the amount of electric charge that crosses a surface in 1 second when a steady current of 1 absolute ampere is flowing across the surface.
-
1 absolute coulomb = 10 coulomb
- 1 absolute coulomb = 10 coulomb = 3.00×1010 statC
