Part of Lesson Plan: **Ohm's Law (updated) By Richie Rizzonelli

Activity Overview / Details

I will give the students the following information: Warning never mix the two because of catastrophic events. I will explain to the students that voltage is the pressure in the hose and I will demonstrate by putting my thumb over the end of hose & explain that the water stream would flow over a distance which can be related to the pressure or EMF (electromotive force.) The Amperage is the current in the hose, when you turn the spiket open, this creates more flow in the hose or more current in the circuit.

Resistance is when you crimp the hose with your foot you are causing resistance to the flow of water through the hose. In a circuit, if you add resistance, you resist the flow of electrons in that circuit.
