Obviously, I need to do some research, because I do not understand any of your explanations. Thank you for actually explaining how these processes work, and enlightening me on the fact that I am of a lower faculty of understanding.

Thank you for telling me what I should do. I apologize for being rude, it's just that I am very uncomfortable when I don't know something. I don't think I should have to feel this way, but thank you for telling me that I can find this in textbooks. I was simply unaware, and my fault has been...

Could you please give some examples, because if I am wrong I don't want to remain that way. I'm sure you understand that as a fellow scientist, and I believe you agree with the ability of people to spread knowledge freely. You don't have to tell me everything in the book, but it would be nice if...

Let's say I want to determine what will happen during a chemical reaction. My current reasoning is that the electrons will be more likely to move from a less electronegative atom first. For instance, cesium is much more reactive than potassium, because its electronegativity is much lower...

I used two aluminum electrodes.

I am running a dc current through a solution of Aluminum Hydroxide and I see a solid precipitating from the negative terminal, and bubbles coming from both terminals. Also, the positive terminal is corroding with little tiny holes in it. What is the solid being produced, and what is happening to...

I have read the entire manual and understand how to use and change every option on my power supply, I know the difference between voltage, current, and resistance, and I know not to do silly things with my power supply and how to maintain it's operation as not to break it. I understand the...

I'm just trying to learn more about electricity, not really messing around with short circuiting (unless you need to short circuit to learn more). I was attempting to use it to learn more about current, voltage, and resistance (which I did) so I'm happy now. But I'm planning to use it for a...

This is my extent of knowledge now: voltage is the measure of potential energy to move electrons from one point to another and it determines the kinetic energy that the current will have. This explains why my power supply can have a voltage without being a closed circuit, because it is showing...

You're right, but I am really curious to learn about how it works and I wan't to use it effectively and safely. I don't want to waste your time and ask you to explain everything to me, however I would like to be pointed towards some sort of resource, because I am having trouble finding one.

Ok, so there can be voltage when there is no current. Why does my power supply say there is no voltage when the current is 0 even though the voltage limit is set to maximum (while the terminals are connected through a piece of metal). Also why does it say there is no current when I set the...

Yes, I understand now what the current value means. What you are saying is that there can be no voltage if there is now current to carry that voltage correct? I did notice that if the voltage knob was turned up to it's maximum, that it would slowly increase as I turned up the current until it...

Thanks for the analogy, but I understood your explanation before it, and I realized how silly my question was right after that post. Thank you for taking your time to explain it though.

Thank you phyzguy, that is the explanation I expected, but I needed to be sure. Also, is there a way that I can measure the current without making it flow through a conductor? If not then that's fine, but I would like to know.

Allow me to explain. When I turn on the power supply (plugged into a wall socket) it has two display screens. One is for current (measured in amps), and one is for voltage (measured in volts, obviously). There are two knobs under each display screen labeled coarse and fine for changing the...
