What is the unit of current in which 6240000000000000000 electrons flow past a given point in a circuit in one second?

The formula for current is I = Q/t [A = C/s]. In Words, current in amps is equal to charge in coulombs divided by time in seconds.

In order to answer this question, you must first calculate the number of coulombs in the specified number of electrons.

Q = (# of electrons) * (elementary charge) = 6.24x1018 * 1.602x10-19 = 0.999648 C

Then substitute this value into the first equation using the given time:

I = Q/t = 0.99648C / 1s = 0.999648 A

If one were to round to the nearest thousandth, this value would become approximately 1 Amp.

Be aware that current moves in the opposite direction that electrons move, even though the rate is the same.
