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.
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.
1 microcoulomb is the equivalent of a millionth of a coulomb.
1 statcoulomb is equal to 3.33564 x 10^-10 coulombs.
It takes 6.25E18 electrons to produce 1 coulomb of charge.
Newton / Coulomb, which is the same as Volts / meter.
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.
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.
1 ampere = 1 coulomb/second 1 coulomb = 1 ampere x second
1 Coulomb = 1 amp for 1 second
The Coulomb. If 1 Coulomb is transmitted per second this is 1 Ampere
1 coulomb= 3*109 statcoulomb
The coulomb. It is the charge transported by 1 ampere of current in 1 second.
That's the coulomb, equal to the quantity of charge moved by a current of 1 ampere during an interval of 1 second.
1 joule per coulomb = 1 volt
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
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.
1 microcoulomb is the equivalent of a millionth of a coulomb.
