I'm trying to simulate a current sensing op amp circuit, my AC voltage,24AC is across a load of 10 ohms, I want to add a 100micro ohm resistor and measure the voltage across it using an op amp, looking into some reference designs as I understand the implementation I have done for a high side current sensing circuit seems to be correct but as you can see there is not voltage change across the op amp output. I also made sure to select an op amp that had a low offset voltage 60 micro volts, could someone please explain what is it I am doing wrong here?

I'm trying to simulate a current sensing op-amp circuit. My AC voltage, 24 VAC, is across a load of 10 Ω. I used a 100 μΩ resistor and measured the voltage across it using an op-amp.

Looking at some reference designs, what I have done for a high-side current sensing circuit seems to be correct, and I made sure to select an op-amp that has a low offset voltage (60 μV), but as you can see there is no voltage change across the op-amp output.

Could someone please explain what I am doing wrong here?
