Electronic electroscope

Abstract— An electroscope is the instrument used to detect charged bodies. Here, an electronic version of the scope that is more sensitive as compared to its conventional counterpart and which helps indicate the polarity of charge has been described. This circuit consumes very low quiescent power and reliably indicates charge induction and detection. The polarity… View Article

Power Supply

Aimed at system designers whose interest focusses on other fields, this note reviews the basic power supply design knowhow assumed in the rest of the book. In mains-supplied electronic systems the AC input voltage must be converted into a DC voltage with the right value and degree of stabilization. Figures 1 and 2 show the… View Article
