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.
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.
I was a communications electronics technician/dealer for 25 years so I know a lot about circuits but I'm also a web geek and I assure you that you can easily find everything you need online by plugging the following search string into google:
basic electronics circuits tutorial
Of course I'll be delighted to answer specific questions about anything which you don't understand after having been through a tutorial.
yeah sure/... i hope my knowledge may find some good use ......
If you have any specific questions you can PM me and i will answer them
Maybe I am not allowed to answers PMs from someone your age
Hmmm if only I'd finished my electrical engineering degree...
For $50 an hour, I think I can arrange it.
