shunt resistor

A shunt resistor is a small device used in electrical circuits to measure current flow. It is designed with a very precise low resistance value so that when current passes through it, it creates a tiny voltage drop. By measuring this voltage drop with a voltmeter or sensor, the amount of current flowing through the circuit can be accurately determined. Shunt resistors are commonly used in applications like battery management, power supplies, and electrical testing to monitor and manage current without significantly affecting the circuit's performance.
