Physics Demonstrations at Cal Poly Pomona

Demo Index:
    EM-F-RW
Pira Index:
    5F 20.40
Title:
    RESISTANCE OF A WIRE
Description:
    Demonstrates linear resistance.
Equipment:
    1. Wheatstone apparatus w/ 2 spade adaptors attached
    2. Fluke 75III Multimeter OR large demo multimeter
    3. 2 B-B leads
Procedure:
    1. Connect as shown.
    2. Use the sliding tap to measure the resistance of various lengths of wire.


    Set multimeter on O. The full length of the wire resistance should read approx. 3.3 O. Half length ~ 1.6 O
