Ok, first, thanks for taking the time for reading my question. Second I need help with these physics laws. I don't get the Faraday's law, the Coulomb's law, or the Ohm's law. Are just formuals are what? I need to explain them in a paper and I don't get them myself. Can you help me please! Thanks again!! = )

Thats are hard question to dumb down. I think you will get alot of anwers with just numbers and equations with no explanation. Because there was alot of year of physics that went into this subject to bring it down to just a few simple eqauiontion. Ill try not to use equations. Ill try to explain what i know
Faraday's law: If you have a magnetic field and change it in anyway. ie. rotating the source, changing the strenght etc. You will cause an electric field to be generated. The direction of the electric field will be that of a loop around the direction of the magnetic field.
Columb's law: If you put charges together, they will repel or attract eachother. With what force will they repel or attract eachother? The columb's law will tell you force they attract or repel eachother.
Ohm's law: If you have to push charge through something it will ecounter a resistance. In order to move charge you will need an electric field and it will have to act along a distance (also known as a voltage). The strenght of this field determines how much you can move a charge. Ohm's law shows that a current can be generated if you supply a voltage, and that current will move slower if you have more resistance and vice versa. Hope that all helped

Yes, they're formuli - but they are explaining... defining... measuring the relationships among variables. It is actually stuff which is applicable to the real world in magnetic effects, induced current - and the magnetic effect of it, and such mundane stuff as what size circuit breaker you need.
And, ignoring the first two, let me address the mundane: Ohm's law simply shows the relationship among the voltage, current, and resistance in an electrical circuit: The current (amount of flow measured in amperes) multiplied by the resistance in the circuit (what that current has to force itself through... measured in ohms) is equal to the voltage "pumping" the current through the circuit. Volts = Amps x Ohms.
Hook that one up with another: Power (Watts) = Voltage x Amps and you have a good start on deciding wire sizes, circuit requirements, fuse or circuit breaker requirements...
Hey! It's all good!

I would love to explain these's laws to you, but that would take forever to truly explain them. Every physics formula you see are more than just "formula." Basically, these laws were first obtained by experiment, and to make things simpler, the results of these experiments are expressed as formulas. You should go to WIKIPEDIA.ORG, and it will explains these things better.
