Purpose

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 rating (not resistance value) and introduces the color-code system for identifying resistance values.

Collection of resistors and passive components including color-banded carbon and metal film resistors of various wattages, wire-wound resistors (one labeled Super Davohm), white ceramic power resistors, small black potentiometers, disc capacitors, and a wire-wound inductor
Figure 1: Assortment of passive circuit components including various resistor types (color-banded carbon film, wire-wound, and ceramic) alongside capacitors and an inductor for comparison. Note the different physical constructions reflecting different power ratings and resistance values.
