A versatile meter for capacitors The two most important properties of a capacitor are its capacitance and its internal resistance (ESR). You need to know both values in order to judge whether a capacitor is suitable for a particular application. The meter described here combines two popular Elektor Electronics projects to create a convenient new instrument that rightly belongs in every well-equipped electronics lab.
measures capacitance as well as ESR
