How to Make a Shunt Resistor

Last Updated on January 23, 2024 by Swagatam 6 Comments

shunt meter compressed

A shunt resistor is a very low value, high wattage resistor which is connected in parallel to a low range meter, so that it helps the meter to substantially increase its measuring capacity. Quite often you might find it hard to measure large currents with a contemporary multimeter. If you’ve ever considered buying an industrial shunt to address […]
