Important question! For electricians

[Nobody]

So i was thinking the other day how could i

Explain the reason for using the root mean square value of a AC waveform and relate this to steady D.C. values for resistive heating effect.

But i couldn't come up with a answer. So then i was trying to

Describe the operation of a simple single loop, two poles alternator with slip rings and brushes with the aid of a sketch.

but that had me stumped as well.

Anyone have any ideas? electricians?

RMS value of ac voltage makes (average) power=voltage^2/resistance the same way it is for dc.

Good starting point for alternator is google search for "two pole dc generator"

This is pretty much exactly what you want

Any questions you have I'd be happy to help.

I know that if you are prying an outlet cover that has been painted off the wall you can jab your screwdriver into the wires behind the outlet and blow yourself back a couple of feet.

I thought I understand the problem in high school, until I learned calculus and see the reason.

See amongst my friends im considered the smart one. so one of them was paying me to do his course work that he has to do for work. But while im good at writing reports and such iv got no idea about this crap. So i Google and bluff my way through.

Also im not claiming to be smart im just claiming to be smarter than my friend.
