This circuit is based on a regulator component that consists of a transistor and zener in the same package. The circuit can be designed with the equivalent discrete configuration. The current is 200mA.
This is a bridge for the measurement of low value resistances and high values too. The circuit...
This circuit was found in Radio Electronics magazine from April 1961. The device has a slot for...
We found this circuit in an English publication. The transistor can be a BC558. The instrument can be...
