Hi friends, I am working on a project to measure the contact resistance of a relay.The idea is with a constant current source (10ma) we can measure the voltage drop of the contacts, but it is a negligibly small value(0.1mv or 0.2mv). So i need to amplify it (possibly to 10mv or 20 mv )with an instrumentation amplifier. I am very poor in analog design please help me to design it.
I found OP07 op amp is capable of amplifying very low voltage to a desired value.
Please help.
