【正文】 為了避免接入誤差，采用如圖二所示的“補(bǔ)償電路”。 關(guān)鍵字：電位差計(jì)，補(bǔ)償法 Abstract Potentiometer is an instrument for measuring the potential (voltage) in a circuit. The accuracy of the potentiometer is high and it can avoid the errors made when wires of power meters are connected. But operating the potentiometer is very plex. And it is not easy to achieve measuring automatically. Today, the instrument for measuring the voltage is replaced by digital voltmeters. The digital voltmeter has high internal resistance and it can measure the voltage automatically. So it is used widely. Nevertheless, the potentiometer still has its important value of experiment as a typical application of the pensation method. In addition, paring DCpotentiometer is still the most accurate instrument measuring the high voltage. And it is often used as the standard instrument in the test of digital voltmeters and other preciselymeasuringvoltage instruments. Keywords：Potentiometer, pensation method 2目 錄摘 要 1Abstract 2目 錄 1一、實(shí)驗(yàn)?zāi)康?2二、實(shí)驗(yàn)原理 2 2 3三、實(shí)驗(yàn)儀器 5四、實(shí)驗(yàn)內(nèi)容 5 5 6五、數(shù)據(jù)處理 6 6 箱式電位差計(jì)測(cè)干電池電動(dòng)勢(shì) 7五、討論 實(shí)驗(yàn)內(nèi)容或?qū)嶒?yàn)儀器的改進(jìn)意見與建議 8 8六、實(shí)驗(yàn)感想 收獲、體會(huì)、意見或建議 意見和建議 9七、致謝 10八、附錄 11 11九、參考文獻(xiàn) 12
