🔍 Key Concepts

• Identify how many electrical connection points (terminals) are shown in schematic figure C and compare that to each physical resistor in the illustration. • Recall that a tap or adjustable contact on a resistor is represented in schematics by a short vertical line coming off the zig‑zag symbol. • Look closely for resistors that are designed to be adjusted while in use (sliding contact, knob, or shaft) versus fixed-value resistors.

💭 Think About

• Count the number of terminals shown in schematic figure C and ask: which physical resistor(s) have the same number of separate connection points? • Does figure C show a single adjustable point on the resistor, or more than one? Then, which illustrated resistor has that same style of adjustment or taps? • Compare the mechanical design: does the matching part need to rotate or slide to change resistance across different taps, or is it fixed once wired?

✅ Before You Answer

• Verify that the number of terminals on your chosen physical resistor exactly matches the terminals numbered in figure C. • Confirm that the resistor you pick has a tap/slider arrangement that matches the number and placement of the schematic tap lines in figure C. • Make sure you are not confusing a simple variable resistor (rheostat) with a multi-tap or multi-terminal resistor symbol—double‑check the symbol details.
