If one electron is \$\approx 1.062\times10^{-19} C\$, then if you have 1A of current in 1 second, you'll have a lot of electrons like about 6241509128999772160 electrons. If the charge on an electron is coulombs, how many electrons should pass through a conductor in 1 second to constitute 1 ampere current? Why do we use perturbative series if they don't converge? Then we can see in this example that every coulomb of charge possesses an energy of 9 joules. Voltage is a measure of the pressure that allows electrons to flow, while amperage is a measure of the volume of electrons. Since each electron carries 1.6 x 10-19 Coulombs of charge, a current of one ampere represents a flow of (1/1.6) x 10+19 electrons or 6.22 x 10+18 electrons each second. Named for the 18th19th-century French physicist Charles-Augustin de Coulomb, it is approximately equivalent to 6.24 1018 electrons, with the charge of one electron, the elementary charge, being defined as 1.602176634 1019 C. In practical terms, the ampere is a measure of the amount of electric charge passing a point in an electric circuit per unit time with 6.241 1018 electrons, or one coulomb per second constituting one ampere.

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. The positive charge on a proton is equal in magnitude to the negative charge on an electron. When current flows from a battery, does voltage decrease? When 1 Coulomb charge flow through a wire in 1 second then the current through the wire is 1 AMPERE. The rule of thumb is that the amperes you can actually put on a 20-amp breaker should never surpass 80% of its capacity, equalling 16 amps. Number of coulombs = current in amps x time in seconds. The same idea can be applied with electric current. So, saying that 1 amp is flowing through a wire is equivalent to saying 6.241018 electrons are flowing down the wire every second.
