Apparatus for Studying the Dependence of Electrical Resistance on the Factors that Determine it
Product Code : SCL-PLE-12370
The Apparatus for Studying the Dependence of Electrical Resistance on the Factors that Determine it (SKU SCL-PLE-12370) is a resistance of a wire experiment apparatus for investigating how length, cross-section and material affect resistance. It combines a 2-14 V AC/DC, 6 A power supply, a digital ammeter and voltmeter, test wires of 24 SWG and 30 SWG, including copper and iron, and 4 mm connecting leads. JaincoLab supplies it for school and college practicals.
Specifications
The apparatus consists of a 2-14 V AC/DC 6 A power supply, a digital ammeter, a digital voltmeter, two pairs of 24 SWG wires, two pairs of 30 SWG wires, two pairs of 30 SWG copper wires, two pairs of 30 SWG iron wires and red and black 4 mm leads of 100 cm and 50 cm.

Applications of the resistance of a wire experiment apparatus
The apparatus is used to measure the resistance of different wires from voltmeter and ammeter readings, changing one factor at a time: the length, the thickness (24 SWG against 30 SWG) or the material (copper against iron).
- Showing that resistance increases with the length of a wire
- Comparing thick (24 SWG) and thin (30 SWG) wires to show the effect of cross-section
- Comparing copper and iron wires of the same gauge to show the effect of material
- Calculating resistivity from measured resistance and wire dimensions
- Verifying Ohm's law with the digital ammeter and voltmeter
