what is the eletrical measure of current?

Question

i wonder what it is?

Answer 1

Amperes, referred to as amps. It is the flow of one coulomb of charge/second.

Answer 2

The unit of measure is Amperes, amps for short.

This unit is based on the NUMBER of electrons going past a given point in a certain amount of time.

If you are an older student, ready to get technical, just google AMPERE UNIT DEFINIITION.

You will also have to check out COULOMB.

Amps, Ohms, and Volts are all named after famous scientists. Each unit is carefully defined. They have a mathematical relationship to one another.

Higher Voltage works like higher pressure does for a water pipe --more CURRENT (AMPS) going through the circuit components or wire.

Ohms is RESISTANCE. Higher resistance counteracts voltage, thus reducing the current. Analogous to having a water pipe with a smaller inside diameter.

Some materials are CONDUCTORS and some are RESISTORS. Some are NONCONDUCTIVE.

Conductors are usually materials wherein the outer atomic electrons are relatively free to move.

Silver, gold and copper are very good conductors of electricity. But science is now working on superconductors (almost no reistance, or no resistance).

Important formulas: E= IR and R=E/I and I = E/R

Power (Watts) : P = IE so P = I^2 *R also

((if you know how to work around with equations).

Things get too hot when conducting too much current, starting a fire or burning up.

The more Watts your appliances have that are plugged into a single outlet, the more likely you are to exceed the AMP rating of your fuse. The fuse blows, thus preventing a FIRE.

Well, that is some for you.

Probably no best answer here; the combination of all correct answers should be very good though.

You have to think about all of this many times for many different problems before you get a handle on it that produces what I would call fundamental electrical understanding.

The latter knowledge is very, very, very useful in life, even everyday ordinary life. Saves some grief which less knowledgeable people often stumble into, occasionally loosing their lives.

Answer 3

Amperes

Answer 4

Ampers or amps for short or A for an even shorter way.

Answer 5

Ampère (s)

André Marie Ampère French Scientist in the field of Electromagnetism gave his name to the phenomenon.

He invented the following expressions : Current and Voltage ( electricity)

He was working on phenomena induced by currents flowing.

Answer 6

Amperes (amps)

Answer 7

Don't blame you for asking this 'cause it would take all of, oh....at least 5 seconds to look it up with Google.

Answer 8

It is the Amperre, which is often shortened to amps.
