electrons per AMP ?

[Gaston]

Hi guys! would you be kind enough to give me' wirtten in number and in words ,the amount of electrons needed to create an AMP.
I have two references but both have a diference in between so I believe you might be able to give me a more acurate answer?

I don't think there's an accurate number, given the answers are written in scientific notation format.

6.24x10EE18, or 6,241,507,648,655,549,400, or 6.24 billion billion is what I have.

The dictionary I consulted says:

A standard unit of electrical charge. Pronounced "kool-ahm," one coulomb (C) is equivalent to one amp of current flowing through a conductor for one second. It is also equal to 6.25 quintillion electrons (6.25 X 10 to the 18th). From French physicist Charles de Coulomb (1736-1806), who measured the behavior of electrical charges.

The differences may be due to the technical definition of an 'amp' is currently under review, and the actual number may change.

Awsome!

Awsome!

Thank you guys ! it is close to the answers I had received and it will allow me to express in number,to my co workers, how small is an electron.

The number is Avogadro's number. My dictionary states that it is 6.02 X 10^23.
It is named for Count Amadeo Avogadro.
I think it is also the number of atoms in the atomic weight. That is, if you have 2 grams of Helium, you would have 6.02 X 10^23 atoms of Helium.

Yeah, but when them little buggers gang up on ya, they can hurt like heck!

avogadro's number refers to the unit known as a mole:

the coulomb refers to one amp-second
http://en.wikipedia.org/wiki/Ampere


I don't know if the numbers have a basis in the same physics, but they are not the same number (by several orders of magnitude)

Yes, they hurt, and they always seem to come in the billions and billions :grin:

You guys are too smart for me.

you arer right about that . We had one of our guys get hit wit 277 ! this week , but luckly it was only one leg and, as DON ADAMS from GET SMART would say...."Missed it bythat much!!!!"

 

[480sparky]

Yes, they hurt, and they always seem to come in the billions and billions :grin:

 

[quogueelectric]

Yes, they hurt, and they always seem to come in the billions and billions :grin:

And fromwhat I understand it is the same little buggers that keep coming back to bite again and again. At least with AC current. If it is a billion billion how may of thier razor sharp teeth are there??

The number of electrons depends on how long the "amp" flows.

There is a coulomb of electrons in an Amp-second.

I am really impressed how fast my Ammeter can count.:grin:

And calculate it for an RMS reading!

In science and chemistry the number is 6.24 x 10 to the 18th power electrons per second.
In electrical work, we talk about amps per hour. So the number is 3600 times bigger. 2.25 x 10 to the 22nd
This is why you will see different numbers. Just ask if it is per second or per hour.

The older I get and the more I read here, the dumber I feel.

It's not really "amps per hour", it's amps X hours. The word "per" usually means to divide. For example, "Miles per hour" is Miles divided by hours.

Amps aren't something you can count, like feet or miles. It is a rate of change like "miles per hour". Specifically, it is the rate of change of charge.

To get the number of electrons that actually cross a point, we have to integrate the amps over time. For our original post, that just means we have to multiply the amps by the amount of time.

I'm sure everyone understands this, but I just hate to see the language get so relaxed that we use phrases like "electrons per amp" or "per" when we mean "multiplied".

Amps are something you can count-that is what this post is about. I tell my class to picture amps as tennis balls. Amp is number of electrons (or a group of electrons) moving past a point over a period of time. Amp means nothing without a time frame. 5 amps tells us nothing, 5 amps per hour is a definite rate of flow. Of course in electrical work, we assume "per Hour," whenever you see amp mentally add "per hour" to it. Except in science it would be .0014 amps per second. My brother runs 10 miles per hour, he also runs 240 miles per day.
The multiplying is used when you want to find out power, watts: 5 amps x 120 volts = 600 watts (per hour)
