Investigate how resistance depends on length and wire thickness
The Resistance Wire Board is a classroom apparatus designed to investigate how electrical resistance depends on the length and diameter of a conductor. It allows students to collect quantitative data and explore resistance relationships using real measurements.
Mounted on a durable base, the board features four 50 cm nichrome wires with different diameters, providing a clear range of resistance values. A built-in millimeter scale makes it easy to measure wire length directly, supporting experiments that relate resistance to length and cross-sectional area. Standard connections allow quick integration into typical circuit setups, making the system reliable, repeatable, and easy to use in classroom labs.
