It doesn't bleeping matter! One side or the other is positive or negative compared to the other side. Pick one. There are several pairs of materials that create static electricity. One of them will come up lacking electrons and the other will come up with the surplus stolen from the first one. The only thing that matters is a difference in concentration. Pick one and its positive. Pick the other one and it's negative. Why are you asking me to pick one? I said in the link that I don't know. It's different for each of several pairs of materials
- I was just asking if were able to clarify.
-alright.One of the problems is the symbols we use in math to describe this current movement.
We use the plus sign and the minus sign to indicate the Polarity of Voltage.
Unfortunately, instead of using left and right, or in and out, or back and forth, for direction...........we use the plus and minus symbol for the Direction of Current also.
-yes.
This probably comes from the number line in math.
-yes.
This means the when you say positive voltage, it refers to polarity, but when you say positive current, it refers to direction. This confuses many.
-me included.
The other stumbling block for many is the fact that current is voltage in motion and voltage is current at potential rest.
-alright.
Current and voltage are the same thing.............charge.
-alright.
This does not mean that you need 1 C of charge for each volt. Electrons are repulsive and elastic and bouncy.
-alright, but does it mean you need I volt for each C.
Like a compressed gas confined to the conductor surface.
-alright.
We can charge(compress) 1 C of charge to many volts. This elasticity continues with the absence of charge also. The net positive charge left by the absence of electrons is elastic also.
Free electrons are Extremely bouncy. We can charge one tiny electron to millions of volts. How can that be? Pressurize it with a voltage field.
-alright.
Any voltage gradient of a few hundred volts can ionized air and throw a spark a short distance.
-alright.
It doesn't have to be + and - voltage. One electrode could be -100 volts and the other -1500 volts.
-yea alright.
There is positive ion flow within the spark among the air and moisture molecules, but not between the charged objects, unless they are very hot.
-alright.
There is no proton flow(real positive charge flow) between the charged objects, unless they are heated to plasma(the separation of negative and positive charge within the atom with heat) while remaining charged. NOW, protons will flow.
-alright.
We can also induce ionic and electron flow in solutions, not using heat or voltage, but by using chemical pressure.
-yea.
A battery converts chemical pressure into electrical(voltage) pressure.
- doesn't polarity command in which direction charge will flow.[/QUOTE]The polarity of the charge carries is irrelevant (in almost all situations). It is the flow of charge that matters -- electrical current is DEFINED as the flow of CHARGE.
--an answer would help.
