Technical Field

[0002] Resistance is a physical quantity that represents the magnitude of a conductor's resistance to electric current in physics. The greater the resistance of a conductor, the greater the resistance of the conductor to electric current. Different conductors generally have different resistances. Resistance is a characteristic of the conductor itself. Resistance will cause changes in the amount of electron flow. The smaller the resistance, the greater the amount of electron flow, and vice versa. The resistance of the conductor is usually detected by a resistance detection device.

[0003] Resistance detection is an important test task in the electronic and electrical fields, used to evaluate the working status of electrical components or circuits. However, existing resistance detection technology has some shortcomings. Due to the small size of bridge resistors, it is inconvenient to detect bridge resistors, which reduces the efficiency of bridge resistance detection. Therefore, we propose a bridge resistance detection device to solve the above problems. Utility Model Content
