Review Notes

Current Electricity: flow of electrons

“ water in a river”

Static Electricity: stationary electrons;

build up of electrons

“water in a bottle”

Static Discharge: release of electrons

Lesson Notes

Electric Current: continuous flow of electrons through a material (current electricity).

Ampere (amp, A): amount of electrons flowing each second; measures rate of electric current

Voltage (volt, V): amount of pushing force (EMF) by electrons flowing each second.

Lesson Notes

Electric Circuit: closed loop; complete unbroken path through which electrons flow. If electric circuit is broken, electrons will not flow.

- If switch up, broken circuit, electrons / electricity does not flow.

- If switch down, closed circuit, electrons / electricity can flow.

Lesson Notes

Conductors: materials that allow electrons to flow (move). Examples: metals, water, acids

Insulators: materials that do not allow electrons to flow. Examples: rubber, glass, rock, plastic, wood, fabric, ceramic, paper.
