Why is the Wheatstone bridge configuration almost always used for sensors over a simple voltage divider? [duplicate]
Everywhere it seems to be taken for granted that a Wheatstone bridge is more precise, accurate etc. I don't see why it would be any better than a voltage divider if I am directly measuring the voltage ...
