Resistance Characteristics Concept

Displays a collection of resistor types — wire-wound, ceramic, and color-banded carbon/metal film — so students can see how resistance is physically implemented. Illustrates that physical size correlates with power …

Shows that resistance scales linearly with conductor length using a wire-wound rheostat and demo multimeter. Students observe direct evidence for by sliding a contact along the resistor and watching the …

Students observe that resistance is directly proportional to conductor length by varying the effective length of a wire-wound variable resistor. Simultaneous voltage and current measurements allow real-time calculation of at …
