I am doing a project on strain gauges. I have the thing set up in a half-wheatstone bridge. Using a pair of strain gauges im trying to measure the weight!!(attaching each one to a side of a ruler/cantilever and bending it by attaching weight to the end) So heres a confusing bit. I no when the gauges are unstrained the reading on the bridge shud be ZERO(i.e bridge is balanced) I'm measuring the voltage difference across the bridge not current. The point is when i bend them i get a reading(which i shud) Am i correct in assuming that the resistance difference across the bridge when i bend it. This will b recorded as a voltage change? SO heres a question. If i bend it more the resistance difference should b greater so should i get a bigger reading (voltmeter) on the scales or not?? I no the explaination isnt a perfect . PLease bear with me.
