Resistance in a Wire
Learn about the physics of resistance in a wire. Change its resistivity, length, and area to see how they affect the wire's resistance. The sizes of the symbols in the equation change along with the diagram of a wire.

Teaching Resources
Main Topics
- Resistivity
- Resistance
Sample Learning Goals
- What characteristics of a resistor are variable in this model?
- How does each affect the resistance? (Will increasing or decreasing each make the resistance correspondingly increase or decrease?)
- Explain your ideas about why they change the resistance.
