Wrong analogy[change source]

I removed the following analogy (traffic on a highway) because it illustrate the "current" in a wire, not the "voltage". Maybe a better analogy would be people waiting to enter a rock concert, the more there are people, the more they push on each others, but they get nowhere because the door is closed; The pushing on each other is like the voltage, when the door opens and people start to move it's like the current, and the size of the door is like the resistance.

"An easy way to think of voltage is by thinking of a city highway, which represents a wire. On this highway are cars, which represent electrons. The flow of traffic/electrons represents voltage, and is affected by the width of the road, which represents resistance."

Spelling[change source]

"Because it is similar in spelling with voltage, some scientists had made suggestions that it should be called electric tension."

Erm, 'voltage' is spelled exactly the same as 'voltage'. What word was meant here? Or am I missing something?

No idea. The EN version doesn't mention it and Wiktionary is silent as well. I've removed it. --Philosopher Let us reason together. 16:08, 23 June 2009 (UTC)

Volt and Voltage[change source]

The Volt and Voltage are 2 very separate things. Unfortunately I don't know the simplified term for them. Um in simpler terms what would the volt be considered?

1) A measure of energy available to move electric charges through a circuit
2) A force that makes electrons move
3) A unit used to measure how much a material opposes the flow of electrons
4) Depends on length,diameter, material, and temperature
5) the amount of current passing a point in the circuit each second

Answer from Joc: The "volt" is the unit for the voltage, and the "voltage" is what is being measured, in other words, the difference of electric tension between two points is the "voltage", and the measurement you would get is a certain number of "volt", for example, the voltage from a typical wall outlet is 120 volt.

Joc is correct - the volt is none of the above. It is a unit of measure equal to 1 joule/coulomb. I want to add that the volt is a unit of measure for Electric Potential in addition to the aforementioned Electric Potential Difference or Voltage. Electric Potential Difference is the 'true name' and it is called Voltage. Voltage or Electric Potential Difference is the difference in Electric Potential between two points.
Volt and Voltage differences can be seen in the edits I just made to the page.
I have been in the electric field almost all my life (electrician and then electrical engineer) and never heard the term electrical tension used in any other manner than 'high tension line'. Voltage can in some sense and used to be called electric tension, that is why high voltage line is called high tension line. But using high tension as a name for voltage is archaic and should not be used any longer. I would abhor its use on the voltage or any other page here. Bob.A51 (talk) 10:25, 24 January 2018 (UTC)

What is this below?[change source]

It seems like spam and/or improper use.
This seens like an advertisement for some homework help.
I hate to erase anything on a talk page but it looks to me like this should be reported and deleted.

I deleted it. -- It is spam about homework help and 1/2 of the 2 comments is unsigned.
You can find it in the change history if you want or care. Bob.A51 (talk) 10:31, 24 January 2018 (UTC)

Electric Tension[change source]

It has been suggested here and on other pages that another name for Voltage is "Tension" or "Electric Tension". This is not true.
In the common colloquial term "High Tension Line", tension does not mean or refer to voltage. It refers to the mechanical tension in the wires hanging between the electric towers.

In the distribution of electricity, poles or towers are used with wires strung between them. In towns and neighbourhoods poles are generally used (unless underground) and the voltage of the primary wires at the top of the poles may be 5,000, 13,000, or maybe even 25,000 volts. (The voltage of the secondary wires lower on the pole might be from 100 to 250 volts; and the low voltage (less than 50 volt) telephone, cable, and alarm wires are even lower on the pole.) The poles are usually 100 to 300 feet apart and the wires are generally from size #8 AWG to possibly #2 AWG. (In wire gauges the smaller gauge number is a larger wire and #2 is a larger wire than #8 wire.) The weight of the wire based on its gauge and the length between poles creates a mechanical tension in the wires.

In primary distribution between sub-stations and cities larger, higher towers or pole structures are used. These carry voltages up to a few hundred thousand volts, maybe 100,000 to 500,000 volts. The towers are spaced farther, maybe 400 to 1,000 feet, apart. The wires are also of a larger gauge, possible #4 to #000 AWG. Due to the greater weight caused by the larger gauge wire and greater length between poles a greater mechanical tension, or "High Tension" exist in the wires. When referring to High Tension lines the reference is to the mechanical tension.

It just so happens that High Tension lines are also High Voltage lines.
(But then again, the primary wires at the top of the neighborhood poles carrying 5,000 to 25,000 volts are also high voltage lines compared to the 120/220 volt secondary lines lower on the poles.) The U.S. National Electrical Code defines high voltage as any voltage over 600 volts and low voltage as less than 50 volts. In electric power distribution engineering, common usage is that high voltage is considered to be that over 35,000 volts.Bob.A51 (talk) 08:39, 2 May 2018 (UTC)
Joc (talk) 15:20, 5 May 2018 (UTC) My mistake, in French the word for voltage is "tension", and has a double meaning, in English it refers only to the mechanical pull, so you're right, tension should not be used here.
