Topic: DC Ammeters

What is a shunt?

Simply put, a shunt is a resistor. In ammeter applications, a low-value resistor safely bypasses (or “shunts”) current flow around a precision voltmeter. The voltmeter measures the voltage drop—typically in the millivolt range—across the shunt resistor and displays a number corresponding to the current flowing through the shunt.
