i need a circuit for Measure 1ma current with 0.1ohm shunt resister in AC

Category: Hardware
Product Number: AD8410

How can I measure 1mA of current in an AC circuit with 230V using a 0.1-ohm shunt resistor?

I'm working on a project where I need to measure the current of an AC circuit with 230V , specifically 1mA to 5A. I plan to use a 0.1-ohm shunt resistor to do this, but I'm unsure about the best way to measure the voltage drop across the shunt resistor and convert that to the current value in an AC circuit.

Could anyone help with the following?

  1. What type of instrumentation or amplifier would be best for accurately measuring the voltage drop across a 0.1-ohm shunt resistor, especially in a 230V AC circuit?
  2. How can I account for the AC nature of the current (i.e., how should I handle the AC signal to get a consistent reading)?
  3. Are there any specific circuit configurations, components, or precautions I should consider for safety, especially with 230V AC, and for accuracy?

The goal is to construct a simple and reliable circuit for this purpose.

Thanks in advance!
