1. Low resistance value shunt resistance Principles
A low-value shunt resistor utilizes the principle of current division to achieve accurate current measurement. It directs the measured current through the shunt resistor and measures the current passing through it to calculate the actual current value. The current value is typically calculated using Ohm's law (I = V/R), where V is the measured voltage and R is the resistance value of the shunt resistor.
2. Low resistance value shunt resistance Structure
A low-value shunt resistor typically consists of a low-resistance resistor and connectors. The resistor is made of high-precision materials to provide an accurate resistance value. The connectors are used to introduce and extract the current to and from the shunt resistor.
