**One coulomb the charge has actually the equivalent charge the 6.25x10^18 electrons.**

One electron has a charge identical of 1.6x10^-19 coulomb. This is written as 1.6x10^-19 C = 1 electron.

To gain the value of 1 C, both political parties of the equation need to be divided by 1.6x10^-19. This is written as 1 C = 1/1.6x10^-19 electrons. Dividing 1 by 1.6x10^-19 offers a value of 6.25x10^18 electrons every coulomb.

Given this value, the number of electrons passing with a circuit over a offered time can be calculated. One ampere equates to 1 coulomb per second. Therefore, a vacuum cleaner through a 3.5-amp motor uses 3.5 coulomb per second multiplied through 6.25x10^18 electrons/coulomb, or 21.875x10^18 electrons per second. That is 21,875,000,000,000,000,000 electron every second!

This equivalency can likewise be provided to identify the variety of electrons compelled to execute a provided amount of work. Given that 1 volt equates to 1 joule/coulomb, a circuit creating 18 joules of work off that a 9-volt power source would call for 2 coulombs worth of charge, or 12.5x10^18 electrons.
