This simple source with zener regulation is ideal for experimental projects with operational amplifiers. Other voltages can be obtained by changing the zeners and the transformer.
The circuit shown consists of a bilateral constant current source with an operational one that...
This circuit for discharging NiCad batteries limits the current to a value that can be adjusted in the...
This AC voltmeter, with 10 V full scale, has a sensitivity of 20 k ohms per volt. The supply must...
