How Do You Calculate Charge and Electrons for a Hair Dryer Drawing 9.7 A?

[aznangelcakes]

A hair dryer draws a current of 9.7 A.

(a) How much charge passes through the hair dryer in 3.5 min?
C
(b) How many electrons does this represent?
electronsi am sick and i have the homework due tomorrow so i really have no idea how to do it.

That you don't know how to do a shows a serious lack of understanding of a concept like current. So I suppose that you first read your text or my post here so that you know what you are talking about. Hopefully you will then see that a) is extremely easy, once you get the definitions right.

Look at the units of an Ampere.
Look at the charge per electron in Coulombs.

These are very basic questions to see if you understand the meanings of the quantities. If you understand then the solution is relatively obvious. Look up the definition of units of current in your textbook.

yup thanks compu chimp i get it now :)...ive been sick for a week fyi ><

Being sick is annoying (apart from the fact that you're not feeling well for a while, of course), because you have to catch up with a lot of material.

BTW, if sickness prevents you from handing in your homework in time, you can always ask your teacher to grant you a delay.
