If you want to measure resistance and you know Ohm’s law, it seems like you have an easy answer, right? Feed a known current through the thing you want to measure and read the voltage required. A ...

Power supplies use control-loop circuits to produce constant voltage or current. The transfer function—gain and phase as a function of frequency—provides valuable information about a control loop’s ...

Part of Design and Technology Electronic and microelectronic control systems Using Ohm’s Law (V=ꞮR), you can calculate the expected values for voltage, current, and resistance in a circuit. Ohm's law.

A version of Part 1 appeared in the Dec. 2011/Jan. 2012 issue of Test & Measurement World. See the PDF. In January 1979, Electronic Test published an article claiming that a single test circuit that ...

A proposed ASTM International standard will be used by engineers, concrete producers and testing agencies to measure electrical resistance in fresh concrete. Participants are welcome to join the new ...
