Wheatstone Bridge with strain gauge explained

Подробнее о видео

By using an instrument called Wheatstone's resistance measuring bridge, unknown resistance values can be determined very precisely. This can then be used to infer, for example, temperature, light intensity, or mechanical deformation due to a specific mass. From the content:
