The op amp-based current sensing circuit described here is not new, it has been around for some time, but with very little discussion of the circuit itself. Somewhere along the line it was informally ...

Find the voltage v1 and the currents I1 and I2 for the circuit shown. To solve this problem first find the total current going through the 14 ohm resistor. To do this find the effective resistance of ...

Andy recommends favorite resources for basic op amp circuits and includes a portion of TI's AN-20. Test your knowledge with our op amp quiz; answer explanations are included. By 1969, a fledgling ...

Short-circuit currents represent a tremendous amount of destructive energy, which can be released through electrical systems under fault conditions. Baseline short-circuit studies should be performed ...

Protecting circuits and equipment from overcurrent from overcurrent involves more than simply selecting a fuse or breaker from a table Art. 240, which is divided into ...
