What Is a Current Sense Resistor?
A current sense resistor is a device that detects current flow in an electrical circuit.
It employs a resistor with a low resistance value. When current passes through this resistor, a voltage drop occurs across it. This voltage drop is used to measure the current's magnitude.
Current flow through the resistor can cause changes in its resistance due to heat generation. Consequently, for high-precision measurements, resistors with stable resistance over temperature variations are preferred. Current sense resistors are utilized in various applications, including monitoring current in control circuits of electronic devices and electric vehicles, managing current in chargers and power supplies, and in overcurrent protection circuits.
