Electricity... I hate it so much...

Ok, I have to write notes for my unit test that is coming soon (date of test is unknown), but I need help with a few things:

-I need to know how to explain how the model of the atom explains static electricity.

-Advantages and disadvantages of alternate energy sources (what is an alternate energy source, anyways?)

-Advantages and disadvantages of series and parallel circuits.

If anyone could help me with any of these, it would be much appreciated.

omg when i saw the title to this thread i kinda got worryed, lol but dude i know your pain.
and im sorry im not that smart i cant awnser this. ;(

Advantages and disadvantages of series and parallel circuits.

I did that in fourth grade.

Series:
Pro: Energy is pooled for a bigger output. (eg. Lightbulb shines brighter.)
Con: When one energy source diminishes, all sources stop fueling the consumer.

Parallel:
Pro: If one energy source diminishes, the rest will keep going to fuel the consumer.
Con: Not as big of an output. (eg. Lightbulb will be dimmer than if it were wired in series.)


Hopefully that'll get you on the right track.

Sorry, can't help with the rest.

1. Well in a normal atom there are the same amount of protons, neutrons and electrons...these are dependant on what type of element.

Protons are positively charged, Electrons are negatively charged and neutrons have no charge.

When either these pieces of an atom are taken away or added they are to be seen as statically charged. If you have more protons than electrons, the atom is positively charged...it it is the other way around it is negatively charged.

2. I think I know what you are talking about. e.g. hydroelectricity, wind power, solar energy (I think that is what you mean)

Advantages - They are cheaper in the long run, sustainable energy and good to the environment.

Disadvantages - Expensive at the start to install, need heaps of land to accommodate for alternative energy i.e. windmills have to be put strategically, have to dam up water to use it, need a wide amount of space to get the amount of sun that is needed in comparison to fossil fuels.

3. Series (as said by Link_315 earlier)

Advantages - Simple to use, as Link_315 said it has a bigger output.

Disadvantage - If one light goes then all go (like with old Christmas Tree lights)

Parallel

Advantages - All lights stay on if one blows.

Disadvantages - Lower outage, could get complicated

Well there you go, I hope that I have helped. Fear my electrician knowledge.

Thanks for the help, people. Finally, I can get some rest for a few days from doing this stuff.
