What affects resistance
R depends on material, length, and cross-section. This “What affects resistance” page is an MVP interactive sketch — formulas, controls, and live readouts in the browser; a fuller bench may follow.
R depends on material, length, and cross-section.
Key formulas
R=\rho l/S
How to use
- Adjust parameters in the left panel.
- Use play / pause and speed controls.
- Match right-side readouts to the formulas.
- Reset to return to the initial state.
Applications
- What affects resistance: R depends on material, length, and cross-section.
- In class, tune parameters for “What affects resistance”, then check against the textbook result.
FAQ
What does MVP mean on this page?
An interactive sketch with formulas and parameters. Polished Ready labs are the full bench experience.
What does the “What affects resistance” lab practice?
Tune parameters and match readouts to the “What affects resistance” relations — useful for prep and demos.
How do I connect meters?
Ammeter in series; voltmeter in parallel — watch polarity and range.
When does Ohm’s law apply?
For ohmic conductors I=U/R; nonlinear devices need their own curves.
