Large Capacitance Measurement by Multiple Uses of MBL Charge Sensor

摘要

Crecent article by Morsel described interesting elec-trostatics experiments using an MBL charge sensor. In this application, the charge sensor has a largecapacitance compared to the charged test object, so nearly allcharges can be transferred to the sensor capacitor from thecapacitor to be measured. However, the typical capacitanceof commercial charge sensors is 10 nF, which is quite smallcompared to general capacitances for electric circuit experi-ments. In this paper, we will describe how to use the com-mercial charge sensor to measure a large capacitance.
