This circuit was found in a 1977 documentation. It limits the voltage from a source using zener diodes on the rectifier bridge. It is an unusual configuration today.
Found in a 90s Silicon Chip documentation, this circuit provides a current of 3 A and the voltages...
We found this circuit in a Japanese publication in 1967. The circuit consists of a 15 W audio...
This is a bridge for the measurement of low value resistances and high values too. The circuit...
