I have very disappointed myself. I am forgot how count time, if car drives example 45 km(kilometre) distance and it's speed is 100km/h ( kilometre per hour). How i know what is time?
equation is
t = s/v (t = time, s = distance and v = speed)
and now equation is
t = 45km...
If we have function machine, which change numbers 1,2,4 and 7 like this
1 --> 4
2 --> 8
4 --> 16
7 --> 28
How i know simple, what is function, what machine use? :frown:
( I don't speak very well english )
If that is generator. Why it has not iron stick in the middle of coil , because if that coil is copper it dosen't influence with a permanent magnets? I don't know, or must be coil almost made iron. :confused:
OK! But this topic is no more treat Electron move. So I ask, how large force must be...
Are commutators devices, what change current direction? :rolleyes:
I mean if I want make my homemade generator model and it must be act DC or AC and i have a permanent magnets, some coil, iron stick and brushes. How do i make this commutators? I don't want make it, but it must be simplier...
How magneticfield bring off free electrons move in generators coil? Normally generator coil material is copper and this have free electrons in this electron shell and electron flues be composed free electrons.
You mean, when generators coil roll in magnetic field that makes alternating electric field in coil and this electric field give force to the electrons. OK! But what causes influence, do generator make AC (Alternating Current) or DC (Direct Current)?
Hi everybody!
I wan't ask, what force makes electrons move? For example when electricity generator act, what force makes generators coil electricity?
(I'm sorry! My english is very bad and this is my first time when I write something here) :smile:
