Electricity and Electronics

What are electrons?

1. a slightly modern view: https://www.wtamu.edu/~cbaird/sq/2014/02/07/what-is-the-shape-of-an-electron/
2. atomic structure: https://www.youtube.com/watch?app=desktop&v=h6LPAwAmnCQ&t=49s

Watch some videos on how electricity can kill you. Keep notes about the important vocabulary. Be able to explain how electricity can kill you.

Watch these videos in this order:

Measuring resistance:

1. measure the resistance in a resistor
2. measure the resistance in a potentiometer: https://www.youtube.com/watch?v=SECWePatYjY
