    In the 1970s, Ohm's law was so easily explained.

    Well on the course for an electrical qualification certificate (colloquially, SEP), the instructor, in this picture, explained to some people what voltage, current or resistance.

    In total, I have the impression that this picture of the Internet more than visited the world :D

    Perhaps I borrowed my avatar from a book, I do not remember. I've been through too much.

    They systematically explained the issues to the soldiers, unfortunately courses in English.

    It is worth coming back to this, as even technical school graduates do not lurk Ohm, Kirchoff and other countrymen ...


    In mass culture, and this cretinism is repeated people who are considered to be electronics / electricians Ohm's law is the version of "current is spreading on the line of the least resistance", or even more "on the smallest line of resistance." Here at the electrode I also got OPR from such experts.

    It is unfortunate that there is overinterpretation and, as a result, even various heresies. Half poor when a middle school / high school student will say yes, but not a professional electronics.

    In mass culture there is always a conviction that electricity and tension are the same. The above-mentioned sentence is already science-fiction :D

    Exactly, I was faced with the idea that current would flow ONLY through the smaller of the two parallel resistors :cry: greetings

    Sometimes, in the very middle of technical sciences, I will VERY associate with the humanities.

    Indeed, their rhetoric was too much of a sackcloth
    (Marek Tulliusz was in the grave)
    tautology chains, some concepts like flails
    dialectics of the perpetrators of no distinction in reasoning
    syntax deprived of beauty of prosperity


    Gustav Robert Kirchhoff turns over the grave.
    For 30 years, this poem has a dimension for me can be said canonical or biblical, especially this one koniuktiw

    Smaller - size or resistance?
    How size is:
    Someone might have been right - in Wcz systems, as well as inverters where there are pins with a short time, with resistors with the same resistance, but with different size or power, there will be a big difference, the resistor inductance will affect it :D
    And when it comes to different resistances, it can happen differently, the opposite situation may occur.

    And right, but then it was a different situation :)

    Statements of such my "students":
    1. This diagram consists of a resistor with voltage and a second resistor. Two-stage voltage setting because the resistor (1) causes the voltage to decrease in this system
    2. A current is connected to the resistors which causes the current in the circuit to drop
    3. Question how to connect it?
    A: Cable
    Q: Cable? What cable?
    About: Wireless.

    In my school there was such a picture in the electrotechnical workshop.

    This picture of Gulson appeals to me the most. Poor ampere ...
    And by the way, laymen do not distinguish it. Because they don't have to do it (and it comes out later when they look for advice on the electrode :-) ). For them, the words resistance, voltage and current do not exist or are incomprehensible, and the units of the latter two (ampere, volt) are the same as power. For example: I have a 230 W power supply (the symbol W is also unknown). Not that I defend ignorance (and I like this knowledge very much), but apart from my technical interests, I would also live without it as I live (in the sense of my family, housing and professional situation).

    As I am glad that with my speech 5 years ago I was praised in the New Year. It was just a simple matter that the kettle, fridge, ... is only resistance for an electrician. Resistance to the flowing current due to voltage. It is the basis for us, but how many disputes arise?
