How to Use the Bridge Law Calculator

The Bridge law calculator is used to calculate the resistance in a bridge circuit. To use the calculator, follow these steps:

  1. Enter the resistance values for R1, R2, and R3 in the input fields.
  2. Click the "Calculate" button to compute the resistance of R4.
  3. The calculated value of R4 will be displayed in the result field.

Working Principle

The bridge law is a principle used in electrical circuits to determine the resistance in a bridge circuit. The formula used is:

R4 = (R2 * R3) / R1

This formula is derived from the balance condition of the bridge circuit, where the ratio of the resistances in one branch is equal to the ratio of the resistances in the other branch.
