Wheatstone Bridge
This interactive simulator explores Wheatstone Bridge in Electricity & Magnetism. Four arms, G between mid nodes; V_B − V_C and null when R₁R₄ = R₂R₃. Use the controls to change the scenario; watch the visualization and any graphs or readouts to connect the model with lectures, labs, and homework.
Who it's for: Best once you already know the basic definitions and want to build intuition. Typical context: Electricity & Magnetism.

How it works
Classic **four-arm bridge**: **A** is at supply **+**, **D** at **0 V**. **R₁** and **R₃** form the **left** divider (**V_B**), **R₂** and **R₄** the **right** (**V_C**). **G** between **B** and **C** sees **V_B − V_C**. **Null** when **R₁/R₂ = R₃/R₄** (equivalently **R₁R₄ = R₂R₃**). Ideal resistors and a **voltmeter** metaphor on **B–C**.
