K5-32. Resistance Vs Diameter And Length
Purpose
To determine how resistance varies a function of diameter and length for the same material.
Equipment
Digital meter, nichrome wires of 0.0125' and 0.0250' diameter with clip leads and projection mount.

Description
The resistance of two wires of the same length but different diameter can be compared. The resistance as a function of length can be determined by sliding the clips along the wire. Use of high-resistance nichrome wire keeps stray resistance (in contacts, etc.) small compared with the resistance being measured. ◙
