摘要
Abstract
By using two kinds of methods, the formula on the relativesensitivity of single bridge is given. All factors affecting relative sensitivity are analyzed. The sensitivity of slide bridge and its influence on the measured resistance Rx are discussed. The condition of the minimum relative error is theoretically given. That is the place of the balance point should be chosen according to the ratio of the measured resistance Rx to the internal resistance Rg of the galvanometer in order to get the minimum relative error. Thereby, the theoretical evidence is offered to cut down experimental error by choosing best ratio N.关键词
