The voltmeter will read the difference between the two electrometers' buffer outputs, which is equal to the voltage across R2.
电压表将读出两个静电计的缓冲输出之间的差值,该值等于r2上的电压。

Thermocouples and thermopiles are devices that use the Seebeck effect to measure the temperature difference between two objects, one connected to a voltmeter and the other to the probe.
