The difference between resistance and patch resistance: resistance is a physical quantity, which physically represents the resistance of a conductor to current. The greater the resistance of a conductor, the greater the resistance of the conductor to current. Patch resistance is a kind of metallic glass uranium resistance. It is a resistor made by mixing metal powder and glass uranium powder and printing it on the substrate by screen printing. Resistant to humidity and high temperature, with small temperature coefficient.

Resistance is a physical quantity to describe the conductivity of a conductor, which is expressed by R. Resistance is defined by the ratio of the voltage u across the conductor to the current I passing through the conductor, that is, R = u/i. Therefore, when the voltage across the conductor is constant, the greater the resistance, the smaller the current passing through it. Conversely, the smaller the resistance, the greater the current. Therefore, the size of resistance can be used to measure the resistance of a conductor to current, that is, conductivity. The size of resistance is related to the material, shape, volume and surrounding environment of the conductor.
