1 coulomb charge is equal to how many electrons
Coulomb Since the charge of one electron is known to be about 6981160217662079999♠1.6021766208(98)×10−19 C,[7] 1 C can also be considered the charge of roughly 6.241509×10^18 electrons or +1 C the charge of that many positrons or protons, where the number is the reciprocal of 1.602177×10^−19.
Coulomb's law where ke is Coulomb's constant (ke = 7009899000000000000♠8.99×109 N m2 C−2), q1 and q2 are the signed magnitudes of the charges, and the scalar r is the distance between the charges. The force of interaction between the charges is attractive if the charges have opposite signs (i.e., F is negative) and repulsive if like-signed (i.e., F is positive).
