Resistance Board
Product Code : JL-LEP-10382
The Resistance Board (SKU JL-LEP-10382) is a 650 mm channel-type plastic board carrying four 600 mm test wires, two nichrome wires of 0.25 mm and 0.5 mm, one stainless steel and one copper wire, with decimetre graduations along their length. Students use this resistance board to investigate how the length, cross-section and material of a conductor affect its resistance. JaincoLab manufactures it in India for school and college physics laboratories.
Specifications
The resistance board is a plastic channel-type board at least 650 mm long, 120 mm wide and 30 mm high, with four 600 mm wires, nichrome in 0.25 mm and 0.5 mm, stainless steel in 0.5 mm and copper in 0.5 mm, and decimetre graduations along the full wire length.

Applications of the resistance board
With a cell, an ammeter and a voltmeter connected across chosen lengths of wire, students measure how resistance changes with length, diameter and material, and use the readings to discuss Ohm’s law and resistivity.
- Showing that resistance increases with the length of a wire using the decimetre marks
- Comparing the 0.25 mm and 0.5 mm nichrome wires to show the effect of cross-section
- Comparing nichrome, stainless steel and copper wires of equal size to show the effect of material
- Calculating resistivity from measured voltage, current, length and diameter
- Current electricity practicals in secondary physics and first-year college courses
