Electricity is hard

[Rubycon]

The voltage problem was the first issue that crossed my mind -- can I series chain batteries? I moved on to the polarity of the contacts after.

And then I remembered that incandescent bulbs used to work great with dimmer switches and I think I read somewhere that incandescent bulbs are so "dumb" they don't care about polarity -- bla bla bla not electrical engineer, me no know da electrical.



The more I look into the teaching profession, the more I realize that for grades 8 and under during my time in school, the teacher essentially taught what they knew or were comfortable with. I learned English grammar in grade 7, and stocks and geography in grade 5. Not sure what the fuq I learned in the other grades.

If I become a teacher, my kids are learning a lot about civil engineering, computers, history, and financial stuff.

It gets hard to hold more than two cells in series with just your hands as well as keep sufficient pressure on both ends AND the lamp base! 😉

Homopolar motors are the simplest to make.
If you have access to a vacuum pump a radiometer is also pretty easy.
