How electricity moves through matter
What resistance really is inside a metal, and why some materials lose all of it when cold.
Start the series- What is resistance, if electrons do not hit atoms?From measured numbers: an electron in copper passes about 150 atoms before one deflection. Change metal and temperature to see where resistance comes from.
