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.

What is 6240000000000000000?
One ampere of curent is equal to the charge of 6,240,000,000,000,000,000 electrons flowing past a given point in a circuit per second.
what term describes the amount of charge that passes a point in a circuit each second Current Resistance Voltage power?
Current
How much current flows through a circuit if 2 coulombs of charge flows each second?
Current in amperes is coulombs per second, so 2 coulombs per second is 2 amperes.
In which circuit does charge reverse direction many times per second?
In an alternating current (AC) circuit, the electric charge periodically reverses direction at a certain frequency. This is in contrast to a direct current (DC) circuit, in which charge flows in one direction only.
How is an ammeter connected in a circuit?
Series connect it within the line of the circuit for which you are interested in measuring the current flow.More detailSince we measure the flow of current IN the circuit, the ammeter must be connected in series with the part of the circuit for which you are interested in measuring the current flow.One of the ammeter's terminals must be connected to a point of the incoming current flow and its second terminal must be connected to the point of on-going current flow. To do this, cut the relevant circuit wire and connect one terminal of the ammeter to each end of the cut.
The unit of current in which 6240000000000000000 electrons flow past a given point in a circuit in one second is the?
The amount of current is measured in units called amperes or amps. One ampere of current is equal to the charge of 6,240,000,000,000,000,000 electrons flowing past a given point in a circuit per second Its in the Penn Foster Book.
What is 6240000000000000000?
One ampere of curent is equal to the charge of 6,240,000,000,000,000,000 electrons flowing past a given point in a circuit per second.
What goes around a circuit?
Charge, in the form of electrons, flow through a circuit. This is called electric current. 1 amp = 1 coulomb of charge per second flowing past a point in the circuit.
If an electric current is flowing through a parallel circuit which units tell you about the amount of electrons traveling in the circuit?
It makes no difference whether the circuit is parallel, series or complex. The number of electrons travelling (or oscillating back and forth for AC) is determined by the current (amps). 1 amp = 1 coulomb/second. 1 coulomb = the charge represented by 6.24150962915265 x 1018 electrons. The current in each leg of a parallel circuit has to be worked out separately.
What describes the volume of electrical current?
Electric current is described in units of 'Amperes' . It's a direct expression of the number of electrons that pass a point in the circuit every second. "1 Ampere" is something like 6,250,000,000,000,000,000 electrons per second.
What is the difference between altenating current and direct current?
The current (or electrons if you will {but thought of as flowing in the opposite direction} in a DC circuit flows only in one direction. In an AC circuit the current periodically flows in the opposite direction (in the US this usually happens 120 times a second, so 60 cycles per second.)
Does adding electrons to the circuit increase the emf?
No. But if you increased the EMF across the circuit, then more electrons would flow through it each second.
What is the name for the flow of electrons in an electric circuit?
A flow of electrons in an electrical circuit is called a current, which is the name given to the amount of electrical charge flowing in a certain period of time.Any total quantity of electrical charge is measured in coulombs.Any flow of electrical current is measured in amps.1 amp is equal to a flow of 1 coulomb of electrical charge in one second of time.
What is the current?
Current is defined to be a flow of electrically charged carriers. These are usually electrons or electron-deficient atoms. It is symbolized by uppercase letter I.
Do electrons flow in only one direction?
Yes. Electrical current only flows in a closed circuit. If it were an open circuit, there would be no current.AnswerAn interesting question. The answer is.... not necessarily! I say this because a capacitor is an open circuit, yet it allows d.c. current to flow for a short period of time (while it charges), and it allows a.c. current to flow continuously.
Are electrons and current the same thing?
No, electrons and current are not the same thing. Electrons represent charge. Charge is simply a difference in free electrons between two points. Current, on the other hand, is a flow of charge, or of electrons, from one point to another. Current, in amperes, is defined as coulombs (charge of electrons) per second past a point in a circuit.
What is alternated current?
That refers to a current in which the direction of flow changes continuously. In household current, this usually happens at 50 or 60 cycles per second (depending on the country), but the definition of alternating current can include just about any other frequency, as well.
