Define 1 Coulomb?? 

Coulomb is the S.I unit of charge.

Charge is denoted by the letter  "Q"

Q = ne where is 'n' is the number of electeons and 'e' is the charge of one electron


For 1 Coulomb,

n = 6.25 * 10^18 (Electrons consitituting in a 1 Coulomb of charge)

e = 1.6 * 10^ -19 (Charge of one electrons)


In statement ,coulomb is defined as

One coulumb is said to be when an object holds a charge of 6.25 * 10^18 electrons. 

NOTE: I have used * as the mulsiplication symbo and ^ as power symbol(exponent)

 thnx a lot!! i knew that it is the SI unit of electricity but did not know the definition!!! thnx agn!! =D

one coulomb is that quantity of electric charge which exerts a force of 9*109 newtons on an equal charge placed at a distance of 1 metre from it.

 The coulomb (symbol: C) is the SI derived unit of electric charge. It is defined as the charge transported by a steady current of one ampere in one second:

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

One coulomb is also the amount of excess charge on the positive side of a capacitance of one farad charged to a potential difference of one volt:

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

1 C = 6.25 x 1018  electron charge ie


ic= 6.25x1018 x 1.25x10-19

  • -34

1C =6.25 X 10 18  X1.25 X 10 -19

 One Coulomb is defined as that amount of charge that repels an equal and and similiar charge with a force of 9 x 109 N when placed at vacuum at a distance of 1 metre from it..

hey hieee...

 the derived SI unit of electric charge; the quantity of electricity transported in one second by a current of 1 ampere....

hope diz hlp...!.cheersss..@@@

  • -63

 one coulomb is defined as that amoun

  • -78

we know that

Q = I.t

so, Q = 1C when

I = 1 A

and t = 1 secs.



1 coulomb is the amount of electric charge (quantity of electricity) carried by a current of 1 ampere flowing for 1 second
