AMP Meter Shunt Calculator
Introduction & Importance
An amp meter shunt calculator is an essential tool for electrical engineers and technicians to accurately measure current in a circuit. It uses a shunt resistor to create a voltage drop proportional to the current flowing through it…
How to Use This Calculator
- Enter the measured voltage drop across the shunt resistor.
- Enter the known resistance value of the shunt resistor.
- Click the “Calculate” button.
Formula & Methodology
The formula to calculate current (I) using an amp meter shunt is:
I = V / R
where V is the voltage drop across the shunt, and R is the resistance value of the shunt.
