WebJan 13, 2024 · A shunt is an accurate resistor that can pass a large current. When the current flows through the shunt, a millivolt-level voltage will appear at both ends of the shunt. So use a millivolt voltmeter to measure this voltage, and then the voltage Converted to current. The large current measurement is completed. III. WebOct 23, 2005 · asdf1 said, "when a resistor fails, it will normally open" . A resistor normally heats up as it conducts current. If the resistor is weakened or defective, that heat can cause the resistor to fuse open. Just like a real fuse, the resistor becomes an open circuit. Last edited: Oct 22, 2005.
