Electric wiring and wires: some basic properties & perhaps unexpected phenomenon

The video goes to the “heart” of one important thing in electronics: the electric wire. The video shows (only) practics.

There is of course a lot much more to tell about wires that conduct electricity and the properties of the materials of which they are made: copper, iron, aluminum, etc, so the material technology.

But this is only a first idea and a video with some essentials that are to be taken in account when we want to work work with electronics.

Some issues in this video: Ohms law, resistance in a wire, contact resistance, soldering and connection properties, a (too simple) touch to the Kirchhoff law, so not explained. Go tot he www for the explanation of Kirchoffs law.

Consider/view this video and reconsider it and review it to get a good first insight in electronics and electronic wiring + its problems and properties. The copper wire in the digital voltmeter ( shunt) was pinched in the factory by workers, to align it to its proper resistance. The pinch marks are visible in the video. That (also) shows a property of a (copper) wire, when it is physically "pinched" that has an effect on the electron flow and (thus) the current that can flow through that quite thick copper wire. On that way by pinching the Ampère meter is "geijkt" (Dutch word, has to do with the Dutch word "ijken"=referenced to a sure/standard value).

All the videos hat I have published on You Tube can be found via my Channel Trailer: Link is


In thematic order you can find these video’s under the “comments” section.
Important: to find all the links to the (+/-700) video’s on my YT Channel, select, in the comments section, “NEWEST FIRST”

My books about electronics are available via the website from “Lulu”, search for author “Ko Tilman” there.



There is an important video via which you can buy a document where I give links to many of my video’s, published between 2010 and 2018.
