A coulomb is a unit of charge. In other words, it's a certain number of electrons, specifically 6.24145 x 1018. It can't be given a radius, much like you can't give a radius to a dozen of cookies.

Can a metallic sphere of radius 1 cm hold a charge of 1 coulomb?

Well I doubt it would be able to hold a charge of that density in air. When a sphere of radius 1cm is charged to such a high level, the electric field will be far larger than the dielectric strength of air. Hence, a breakdown voltage will be achieved and electrons will flow even through air. It's the same principle that lightning works on. 1 coulomb is a huge amount of charge, and the surface charge density in this case will be too high for air to take. So, a sphere of radius 1 cm cannot hold 1 Coulomb of charge.


Can a metal sphere of radius 1cm hold a charge of 1coulomb?

A metal sphere of radius 1 centimeter will not hold a charge of 1 coulomb. The electric field generated from the metal sphere of radiusÊat 1 centimeter will break down and neutralize any charges.

Current is rate of flow of charge, so 1 ampere = 1 coulomb per second. As ampere and seconds are both fundamental units (and coulomb is derived), a coulomb has the dimensions [current][time] i.e. As


What is a Coulomb?

The coulomb is the SI unit of electrical charge. A coulomb, a unit of electrical charge, is defined as the amount of electric charge transported by a current of 1 ampere in 1 second. There are 6.241506×1018 electrons (or elementary charges) in a coulomb. A link is provided to the Wikipedia post on the coulomb.
