WebJul 7, 2024 · A shunt is a low-ohm resistor that can be used to measure current. Shunts are always employed when the measured current exceeds the range of the measuring device. … WebShunts. Electrical shunts are simply devices capable of creating low-resistant path for current. With such, current can flow to another point within the circuit. Electrical shunts can also be called Current shunt resistor (Current shunt) or ammeter shunt. Although the use of a shunt resistor is vast, there is one that is very common.
