Question

define one coulomb charge.

Answer 1

electric charge which is equal to the amount of charge transported by a current of one ampere in one second

Answer 2

Answer:

One coulomb is that charge which repels an equal and similar charge with a force of 9 x 10⁹ N, when placed in vacuum at a distance of one metre from it.

Explanation:

Coulomb's law in electrostatics is an electrical analogue of Newton's law of gravitation. In 1785, Coulomb measured the force of attraction or repulsion between two electrical charges by using a torsion balance.

His observations are known as Coulomb's law in electrostatics.
