Yes, I know that, but, I want to implement some circuit between the drain source and ground, to monitor the voltage. As I know, shall I put the shut resistor between the MOSFET and GND, so that we will measure the voltage, Right?. See below circuit. Please let me know is it correct or wrong and give me some suggestions if I'm wrong.It is always 0v Gnd
You originally posted the drain of MOSFET is 24V and current is passing through is 1A.
This is what your LTS sim shows.
That is example circuit which I have attached above. I want to design a circuit which will read the voltage 24V.hi,
Using a 1R Shunt will give a Vout of around of only 120uV.
After a 2:1 divider half that.
Why do you need to know the Source current and how are you going to use the 120uV signal.??
