This circuit makes use of a 741 single source operational amplifier to measure resistors on a linear scale. The circuit may use as an indicator a common multimeter on a low current range.
This circuit was suggested by Motorola's Linear Databook of 1990. The integrated circuit, uncommon...
We found this circuit in a 1977 Radio Shack brochure. Transistors can be the most modern BC548 for NPN...
This circuit is from an old publication of the 70's. It can be implemented with modern transistors like the...
