Therefore, it is convenient to define a practical unit called coulomb(C) as equal to charge of 6.25 x 10 18 electrons or protons stored in a dielectric. 1.6 into 10 raise to power -19 no of electrons are present in one coulomb of charge. How do you calculate that one coulomb is equal to 6.24x10^18 electrons. $\begingroup$ In a textbook I found it is stated that - " 1 coulomb is that quantity of electric charge which exerts a force of 9 ×10^9 newtons on an equal charge placed at a distance of 1 m from it ". The Millikan oil drop experiment which measures the charge on a single electron provides that answer. 8 years ago. 6 × 1 0 − 1 9 C The charge on an electron is equal to approximately -1.6 x 10 −19 coulomb. A coulomb is a measure of electrical charge and is defined as the charge that flows with a constant current of one ampere (1 amp) during one second. 1A current produced when the charge of I coulomb flows in 1 second.The no. And from this definition we can easily understand and calculate the charge of an electron. 0 0. Maroof. Convert 3 coulombs to electron charge: Under the 2019 redefinition of the SI base units, which took effect on 20 May 2019, the coulomb is exactly 1/(1.602176634×10 ) (which is approximately 6.2415090744×10 , or 1.0364269656×10 mol) elementary charges.
