Training to be an electrician

[leesub2008]

Please Help !

I am training to be an electrician . I am in my first year. At this time we are looking at

series circuits
parallel circuits
power in electricity

and I just need an easy explanation on how to work out how to find the R V I for each of the circuits


any help with this would be great, web site etc or to hear from an electrician

thanks in advance

I typed 'series circuits' in google and came up with
this.

Are these the formulas you seek?

[ACtheTROLL]

the penny will drop ... give it chance

series is a chain ... so you add the resistances one after the other r+r+r
i=v/r , r=v/i v=ir

parallel flows down the legs of the ladder and branches off into each step 1/r+1/r+1/r

capacitors work the opposite way round

but wild's link is good ... just take one step at a time ... don't try to eat it all at once

I think you missed a fairly important part out of parallel, Accybaby:

_____1_____
1/r1+1/r2+1/r3
