What's included
Resistivity Apparatus (Qty: 1)
Resistivity Wire Set (Qty: 1) - SKU: EM-8813
Product Summary
A current is established in a wire of known diameter, and the voltage drop across a section of the wire is measured. Students can calculate the resistance of the wire and the resistivity of the material.
Features
Vary wire length: Slide-wire potentiometer pick-up makes it easy. Use the built-in scale to measure the length of the wire.
Vary wire diameter: Four different diameters of brass wire are included. Investigate the difference between resistance and resistivity. Interchange wires quickly and easily.
Vary wire material: Five different material wires are included. Investigate how resistivity depends on the wire material.
Storage: Built-in storage tray to hold wires.
Sample Wire: Wires are held securely and straight by the wire guides and lugs.
Slide Wire Probe: Spring-loaded wire probe slides easily along the wire, making contact at a single point.
Built-in cm Scale and slide wire probe make it easy to measure the voltage drop across various wire lengths.
