We found this circuit in documentation from the 90s. Instead of a voltmeter, you can use the voltage scale of a multimeter. The circuit tests batteries under load.
This configuration, which uses a transistorized circuit in the feedback, provides a logarithmic response...
This ultra-simple test circuit is of great use in any electronics bench. The power is supplied by a...
This circuit was found in a 1977 documentation. It limits the voltage from a source using zener...
