The Wheatstone Bridge (also known as the Single Arm Bridge) is an instrument that accurately measures resistance. The universal Wheatstone bridge resistors R1, R2, R3, and R4 are called the four arms of the bridge, and G is the galvanometer. Used to check the branch where it is located for current. This software helps users calculate relevant parameters. Use scientific calculation formulas to ensure the accuracy of the calculation results. Come and try it!
