Low ohm resistors in series with current flow will develop voltage as defined by Ohm's Law. Not too sure I fully understand your question.

" ideas on sensing resistors to monitor current flowing "

They have been proven to work based on Ohm's Law. Pretty straight forward.

Any more detail on what you are really wanting to know?

any ideas on sensing resistors to monitor current flowing ?
Low ohm low TC resistors for ball-park estimates, current shunts for moderate currents, high power current shunts for >50 amps.

TC = temperature coefficient of resistance; as shunt/resistor heats up, ohm value changes, results change.

GOOD shunts are supplied with characteristic data that describe how they perform at various temperatures.

Good luck-
:)
