The basic principle and function of current sensing resistor This article introduces the basic principle and function of current sensing resistor, and will explain the current sensing resistor from three aspects: definition, function, and selection. Current sensing resistor is a special type of resistor used to measure the current in a circuit. Its working principle is based on Ohm's law, that is, current is equal to voltage divided by resistance. By connecting a current sensing resistor in a circuit, we can indirectly measure the magnitude of the current by measuring the voltage passing through it.
