Large Capacitance Measurement by Multiple Uses of MBL Charge Sensor
Lee, Jung Sook; Chae, Min; Kim, Jung Bog
Physics Teacher, v48 n1 p42-44 Jan 2010
A recent article by Morse described interesting electrostatics experiments using an MBL charge sensor. In this application, the charge sensor has a large capacitance compared to the charged test object, so nearly all charges can be transferred to the sensor capacitor from the capacitor to be measured. However, the typical capacitance of commercial charge sensors is 10 nF, which is quite small compared to general capacitances for electric circuit experiments. In this paper, we will describe how to use the commercial charge sensor to measure a large capacitance.
