This cartoon helps me remember that Ohm's law has to do with resistance. V=IR is the equation for Ohm's law. V= voltage, I= current, and R= resistance.
Units for V, I and R
The Filament in a light bulb is what gives resistance. The thinner, longer or both thinner and longer the filament is, the more resistant it will be. Resistance also increases the hotter it gets.
This is a fun way to show kids to remember Ohm's Law. Good job!
