Essential QuestionsWhat is the relationship between electric charge and electric current?
What voltage, current, and resistance? How do they affect each other?

Big IdeasElectric and magnetic (electromagnetic) forces can be attractive or repulsive, and their sizes depend on the magnitudes of the charges, currents, or magnetic strengths involved and on the distances between the interacting objects.

open circuit is one where the continuity has been broken by an interruption in the path for current to flow.
![Page 15: Oct. 1, 2020 Yá’át’ééh! sha'áłchíní](https://reader033.vdocuments.net/reader033/viewer/2022060710/62978a1321e26d43d64ed070/html5/thumbnails/15.jpg)
closed circuit is one that is complete, with good continuity throughout
![Page 16: Oct. 1, 2020 Yá’át’ééh! sha'áłchíní](https://reader033.vdocuments.net/reader033/viewer/2022060710/62978a1321e26d43d64ed070/html5/thumbnails/16.jpg)
Which one is an open circuit and a closed circuit?

currents the flow of an electric charge

electric resistance: A measure of how difficult it is for an electric current to flow in a material
![Page 21: Oct. 1, 2020 Yá’át’ééh! sha'áłchíní](https://reader033.vdocuments.net/reader033/viewer/2022060710/62978a1321e26d43d64ed070/html5/thumbnails/21.jpg)
voltageThe amount of energy the source uses to move one coulomb of electrons through the circuit.
1 volt moves 1 ampere

Ohm’s Law a mathematical equation that describes the relationship between voltage, current, and resistance
Named after German physicist Georg Ohm.
States that as the voltage of a circuit’s electric energy source increases, the current in the circuit increases, too.
