| Abstract: | The sensitivity of the electric bridge relates to examine and flow and count with the position connected of power, derive through mathematics and the experiment measure the conclusion of drawing. When D>0 is examined and flowed and connected while counting, the electric bridge is relatively high in sensitivity. Act as D<0 examines and flows it while counting outerly, the electric bridge is relatively high in sensitivity. |
