Basic Bridge Circuits
What are the differences among full bridge, half-bridge, quarter bridge circuits and voltage or current excitation of these Wheatstone bridge circuits?

There's enough difference to present you with a six (6) page detailed application note! Please enjoy the read.

The following link takes you to Dataforth's application note AN117, "Basic Bridge Circuits". This app note explores many of the mathematical relationships among the various topologies of bridge circuits and provides you with enough background information to prepare for the next Dataforth Application Note on Strain Gage measurements.
