Question

How many electrons flow past a point in a wire each second if the wire has a current of 1.00 Amperes?

Answer 1

If the current is 1 Ampere, that means 1 Coulomb of charge will pass through a point in a wire each second.

The charge of one electron is equal to e = -1.602 * 10^-19 Coulombs.

So, to calculate the number of electrons that will have a total charge of 1 Coulomb, we can use the formula below:

`\begin{gathered} Q=n\cdot e\\ \\ -1=n\cdot(-1.602\cdot10^(-19))\\ \\ n=(-1)/(-1.602\cdot10^(-19))\\ \\ n=0.624\cdot10^(19) \end{gathered}`

So the number of electrons is approximately 0.624 * 10^19.
