Watch this first installment in the series on bridge circuits to learn how to make reliable resistance measurements of an unknown part using a Wheatstone bridge.
Compare the Wheatstone bridge measurement approach with alternative techniques such as current measurement and voltage divider measurement. Derive equations and analyze the Wheatstone bridge’s sensitivity to various errors using Symbolic Math Toolbox™. Simulate the Wheatstone bridge using a Simulink® and Simscape™ testbench to emulate real-world behavior and evaluate the robustness of this measurement technique.
