Shunt Resistance

Shunt Resistance is a type of resistor that allows a large portion of the current to be measured to pass over the measuring instrument when we want to measure a large current.

Shunt Resistor is a sensitive device used to measure current in an electrical circuit.

Ohm’s law is decoding for V = I x R or I, I = V / R, where current, V voltage and R resistance.

If the resistance is known and the voltage drop is measured, then the current can be determined.

What is Shunt Resistance? Where is it used?

Shunt resistance is used to measure currents that can damage an ammeter.

This may be the result of the magnitude of the current flowing through the circuit or the possibility of current spikes.

They usually have a small, well-defined resistance so as not to affect the current they are measuring.

A shunt resistor typically differs from a normal resistor,

with one or more metal strips of the two large terminals in conjunction with them.

The resistance of a metal is inversely proportional to its cross-sectional area,

so the shunt resistance shows more strips, lowering the resistance.
