The resistance experimental board is a modular platform designed specifically for electronic teaching, circuit prototype verification, and experimental research. It integrates commonly used resistance devices in a standardized, visual, and repeatable manner on breadboard compatible plugins, helping teachers, students, engineers, and makers quickly build, debug, and measure resistance circuits. Each resistor is printed with a resistance value and color ring comparison table to reduce reading errors. All power resistors are equipped with transparent heat shields to prevent burns. Typical teaching demonstration: Ohm's law, voltage division law, real-time observation of RC charge discharge curve. Collaborate with a voltmeter and ammeter to complete the student experiment on "volt ampere characteristics".
