Potential difference meter

电位差计

Potentiometer (Potentiometer) is a precision measurement of the potential difference in the circuit of the instrument, the accuracy is much higher than the voltmeter. John Cristian Bogendorf studied the potentiometer in 1841, which later became the standard method of measuring the potential difference. The potentiometer combined with the appropriate circuit can be used to measure electromotive force, voltage, resistance, current. The working principle of the potentiometer is the compensation method, which is not divided in the circuit, thus overcoming the general voltage meter in the measurement principle can not overcome the defects (ie, the ideal voltmeter has infinite internal resistance). The potentiometer first needs to be calibrated by the standard battery so that the voltage inside the coil at both ends of the internal differential is loaded. There is a partial pressure between the vane on the coil and one end of the coil and can be compared with the measured potential difference by the galvanometer. If there is a current flowing in the galvanometer, it is necessary to move the vane to adjust the partial pressure until the galvanometer is zero. The divider at this time is the potential difference. The divider can be calculated from the slider position. The principle of compensation method has important application in electrical measurement and other fields. ... 电位差计(Potentiometer)是一种精密测量电路中电位差的仪表,其准确度比电压表要高得多。约翰·克里斯特安·波根多夫于1841年左右研究了电位差计,它此后成为了电位差的标准测实验室量方法。电位差计与适当电路结合,可以用来测量电动势、电压、电阻、电流。电位差计的工作原理是补偿法,不在电路中分流,因而克服了一般的电压表在测量原理上无法克服的缺陷(即,理想电压表具有无穷大的内阻)。 电位差计首先需要由标准电池校准,使电位差计内部的线圈两端加载标准电池的电压。线圈上的滑片与线圈的一端之间具有分压,可配以检流计将它与待测电势差做比较。检流计中若有电流流过,则需要通过移动滑片以调整分压,直至检流计示零,此时的分压即为待测电势差。分压可由滑片位置计算得来。 补偿法的原理在电学测量与其他领域中具有重要的应用。...

Definition of 电位差计 in the Chinese dictionary

Potentiometer use of compensation method for the determination of power electromotive force or voltage instruments. As shown in the slide-type potentiometer. Ab is the line resistance line, e is the power, e0 is the standard battery, ex is the power to be measured. Measurement, first make k contact 1, move the sliding contact c, until the current meter g just no current, uac = e0 = il1; then k contact 2, changing the sliding contact c Position, find the potentiometer balance ac length l2, u'ac = ex = il2. So you can get ex = l2l1e0. 电位差计 利用补偿法测定电源电动势或电压的仪器。如图所示为滑线式电位差计。图中ab为滑线电阻线,e为电源,e0为标准电池,ex为待测电源。测量时,先使k接通触点1,移动滑动触头c,直到电流计g中恰无电流通过时,uac=e0=il1;再使k接通触点2,改变滑动触头c的位置,找到电位差计平衡时ac的长度l2,此时u′ac=ex=il2。于是可得ex=l2l1e0。
