Does anyone fancy teaching me the physics side of electricity? like the circuits and stuff? My teacher won't help me...

I have taught electricity and electronics to people of all ages and skills for many years. I am willing to assist you any way I can but have never attempted to teach via email. It would be interesting to me to see how well it worked. Contact me with your questions, and I will try. It helps for me to know what the chapter titles and books you are using so I can know your skill level and expected outcome. Also let me know your current math skill levels because much of electricity is heavy into math. Dont let that scare you. Like I said I have taught all skill levels into college.

First lesson:

Imagine a dam. Behind the dam is a reservoir of water. The reservoir can be full or empty. The dam can let water out at a slow rate or a fast rate. If the reservoir is full, the POTENTIAL energy that is stored by the dam is high. In other words if the dam breaks, the amount of energy being released all at once would be quite large, and would overwhelm anything down stream. The dam is providing RESISTANCE to the flow of energy, and without some form of resistance, there can be no potential. If the dam fills to capacity the resistance will begin to break down and allow the water to FLOW. We refer to the flow as CURRENT.

One can observe that the relationship between Potential, Resistance and Current flow is relative, that is to say that a change in one will affect another. If the resistance remains constant the current will change with the amount of potential change. Ah, but what if the potential drops to the point that there is no current? I like to think of it as if there is always current of some amount. The dam will always allow a small amount of water thru even if it such a small amount that we cannot measure it.

In the world of electricity, the potential energy is measured in VOLTS while the resistance is measured in OHMS and the current is measured in AMPERS.

Questions?

yeah sure/... i hope my knowledge may find some good use ......

look at electricity as a bunch of lottery balls all trying to get into the same room sometimes coming across small halways and sometimes on one way streets
or if you prefer a transistor , like water going through a tap and the knob being the gate that you can adjust to let the amount through that you require without splashing the water (electricity / electrons) all over the place .
electricity behaves the same way everything else does.
did you know that high power electricity can not go through a conductor when making a sharp turn? it needs a long turn just like a racing car.

For $50 an hour, I think I can arrange it.
