Question

Electric current can be measured. It is a rate. What does that mean?

Question 3 options:

The strength of power used by something plugged into a wall.


The amount of current that passes a certain point in a certain amount of time.


The amount of energy available that could be used.


How bright a light will burn when plugged in.

Answer 1

none of the above :((

it's almost this: "The amount of current that passes a certain point in a certain amount of time." Except that it's the amount of **charge carriers** that passes a certain point in a certain amount of time

Answer 2

hope that is helpful :)

Answer 3

Lol @IrishBoy123 than why would they post it when it's none of those o.O

Answer 4

They are referring to Amp Hours. I am not familiar with the term "charge carriers" perhaps @IrishBoy123 will explain exactly what "charge carriers" are so we can all be enlightened.

Answer 5

@minecraftqueen

The question [expurgated so we can see option b]:

"Electric **current** can be measured. It is a rate. What does that mean?
.....

b) The amount of **current** that passes a certain point in a certain amount of time."

This is circular, yes?!?! Current is the amount of current that passes etc etc is circular.

Current is measured in Amps. From Wiki: "The ampere is equivalent to one coulomb (roughly 6.241×1018 times the elementary charge) per second". So if you count the number of electrons (charge carriers) passing a point in a circuit per second and times it by the charge on an electron, you get the current.

@AloneS

i've been trying to raise a giggle in Physics for a long time now and you've finally delivered for me. Thank you!! Yer fanned :)

@bugman954

ignore all that carrier stuff. in truth, if you are familiar with Johnny Depp's work, charge carriers are just like oompa loompas, only a lot lot lot smaller. this was taken by an electron microscope:



you can see the electrons in their little pockets

yer fanned too :)

Answer 6

oi! you 2 medalled each other!!

Answer 7

The amount of current that passes a certain point in a certain amount of time
The amount of CHARGE that passes a certain point in a certain amount of time

Answer 8

@bugman954 ELECTRONS are charge carriers. They carry the CHARGE ON THE ELECTRON. -1.6^-19 Coulombs. (minus)
Protons are ALSO charge carriers.
They carry +1.6^-19 Coulombs
Ions are charge carriers.
May be that mu mesons are charge carriers though I'd have to check that.
Alpha particles (HELIUM NUCLEI) are charge carriers

Answer 9

Awh @IrishBoy123 that's actually interesting...I've been waiting for you to become my fan or a loooong time LOL

Thank you<3
