The design and construction are simple, it operates with a 9V battery, the output is a led, a buzzer, a multimeter, or an oscilloscope. It is possible to study the kind of electric charge from electrified bodies, obtained from different procedures, quantify it and visualize it.
At this meeting, we present the design, construction, test, and results of this electronic electrometer.
