Water flowing through a hose is a good way to imagine electricity
Water is like Electrons in a wire (flowing electrons are called Current)
Pressureis the force pushing water through a hose – Voltage is the force pushing electrons through a wire
Friction against the holes walls slows the flow of water – Resistance is an impediment that slows the flow of electrons
