What is the charge of one coulomb equivalent to in terms of electrons? (2022)

What is the charge of one coulomb equivalent to in terms of electrons? (2022)

Step 1: Understand that charge is measured in coulombs (C).
Step 2: Know that one electron has a charge of approximately -1.6 x 10^-19 coulombs.
Step 3: To find out how many electrons make up one coulomb, divide 1 coulomb by the charge of one electron.
Step 4: Perform the calculation: 1 C / (1.6 x 10^-19 C/electron).
Step 5: This calculation gives you approximately 6.25 x 10^18 electrons.
Step 6: Conclude that one coulomb is equivalent to about 6.25 x 10^18 electrons.

Charge of an Electron – Understanding the fundamental charge of an electron, which is approximately -1.6 x 10^-19 coulombs.
Coulomb's Law – The relationship between charge and the number of electrons, leading to the conversion of coulombs to the number of electrons.
