and to to the previous posters it's the funny image thread, if you don't like it don't log on.

Thats the best description of the E - I - R and ohms law i have seen in thirty eight years of trying to explain it to the 'lay' person. And by the way, It is correct.

oh no it isn't. You must be an electrician. they teach 'conventional'current flow. The volts should be on the right, looking pretty/ attractive. current flows from earth to the potential. Not the other way around.

but still a good explanation for the laypoerson

Current is taken as flowing from positive to negative, even though the electrons might be flowing the other way

interesting

like myusername, I was ejumikated to ignore the conventional current flow diagrams on the components as it was now (then) considered defunct, electron current flow was gospel, and learn to read/diagnose the circuit in reverse (1990-1991)

maybe it's like english, where one teacher tells you it's okay to start a sentence with "But or And" and another says it's a no no

look put it to bed
they were wrong about the flow of current
they were wrong about the magnetic properties of voltage
they know this now, but mass correction was rendered as unnecessary as it makes no difference to the math and it seems to confuse some
as for marcos assertion that current is not always the flow of electrons. .....well, unless you've discovered matter on this planet that isnt made up of atoms.......what's that, oh you havent discovered that yet, then current is still only made up as a measure of columbs which is a measure of electrons flowing past a point......
end of lesson

Hands up who focused on the red wire looking for the first electron.
