The ETB-195 trainer demonstrates the fundamental technique of converting a galvanometer into a voltmeter by connecting a high resistance in series. It is designed for physics and electronics laboratories to help students understand the principle of voltage measurement using analog instruments. This trainer allows learners to calculate the required series resistance to extend the range of a galvanometer, thus transforming it into a working voltmeter. The circuit setup is educationally valuable for learning about Ohm's law, meter sensitivity, and voltmeter calibration. Key features:
