Spoiler summary: The loop inductance of a circular loop is about 25nH per inch of circumference. Remember: before you start using rules of thumb, be sure to read the Rule of Thumb #0: Use rules of ...

Circuits such as the design described here implement useful tools for a diversity of calibration and testing applications. A two-wire loop current generator is a useful tool for the testing, ...

In electronic systems, wires and cables provide intentional circuit paths for power or signal currents to move from a source to a load and then return to the source. These current paths have the ...
