NGSS: MS-PS2-3: Ask questions about data to determine the factors that affect the strength of electric and magnetic forces.
- Students will understand the electrical quantities of and the relationship between current, voltage, and resistance in order to understand Ohm’s Law.
- Calculate the electric current, voltage and resistance of basic electric circuits.
Electrical circuits are everywhere in our lives, from very complex ones that control computers and smart phones, to the simpler circuits that allow you to switch a lightbulb on and off.
In order to understand how circuits work, we have to understand Ohm’s law, which explains the relationships between the key concepts in a circuit.
