Resistance Board

The resistance board is designed for educational experiments to investigate the properties of resistivity. It features three resistance wires, each measuring 40 cm in length, which allows for controlled experimentation with electrical resistance. Notably, the wires have cross-sectional areas in the ratio of 1:2:4, enabling students to observe how variations in cross-sectional area impact resistance. This setup not only serves as a practical tool for physics laboratories but also reinforces theoretical concepts such as Ohm’s Law and the relationship between resistivity, length, and area.

The board is mounted on a sturdy wooden base, measuring 50 cm long, providing stability during experiments and ensuring that all components remain securely in place. Built-in terminals equipped with 4 mm connections it allow easy attachment of test leads and connecting wires. This setup promotes hands-on learning by enabling students to quickly connect or switch out components as they explore different configurations and resistive materials. The design ensures that the board is user-friendly and accessible for learners of various levels.

Complementing the resistance board are two connecting wires, each measuring 50 cm in length and fitted with 4 mm male banana plugs on both ends. These wires facilitate straightforward connectivity to power sources and measuring instruments, such as multimeters, fostering a seamless experimental process. Together, the entire assembly is not only functional but also durable, making it suitable for repeated use in classrooms or laboratories. By engaging with this equipment, students can deepen their understanding of electrical principles and develop essential skills in conducting experiments, recording data, and analysing results.
