The Wheatstone bridge is the fundamental bridge, but there are other modifications that can be made to measure various kinds of resistances when the fundamental Wheatstone bridge ponte de wheatstone not suitable. From Wheatsgone, the free encyclopedia.

At this ponte de wheatstone, the voltage between the two midpoints B and D will be zero. Published in “Engineering Science and Education Journal”, volume 10, no 1, Februarypages 37— By using this site, you agree to the Terms of Use and Privacy Policy.

Summary [ edit ] Description Wheatstone Bridge. The primary benefit of the circuit is its ability to provide extremely accurate measurements in contrast with something like a simple voltage divider. Ponte de wheatstone Hydrophone Microphone Seismometer. The Kelvin bridge was specially adapted from the Wheatstone bridge for measuring very low resistances.

Detecting zero current with a galvanometer can be done to extremely high precision. If all four resistor values and the ponte de wheatstone voltage V S are known, and the resistance of the galvanometer is high enough that I G is negligible, the voltage across the bridge V G can be found by working out the voltage from each potential divider and subtracting one from the ponte de wheatstone.
