What exactly are you trying to do?
Measuring the voltage across a resistor from the source to ground allows you to calculate the current.
Is that what you want?
No, just measuring voltage how much voltages does it passing through the MOSFET. Monitoring the voltage.

hi pp,
Voltage does not pass thru a MOSFET.
I believe that you mean the 'voltage' developed across the Source resistor due the Drain to Source current passing thru the MOSFET.

As the Gate drive to the MOS is pulsed, so will be that 'current/voltage' across the Source resistor,

How do you intend to convert that 'voltage' into a circuit to give a readable form.?
