Voltage-controlled current sink using Op-Amp Voltage-controlled constant current sink circuit works exactly in the same way as voltage-controlled current source circuit that we built earlier. For a ...

In this article, we will demonstrate the process of building a simple current detector circuit with 555 Timer and some passive components which can help you to detect open live lines with ease.

Current sensing devices are often desired in the power supply lines of various circuits, such as battery-powered computers, battery chargers or critical circuits requiring thermal forecasting. Figure ...

The current-mode or peak-current-regulating switching converter is a familiar, almost dominant power supply circuit. Yet it is one of the most complicated "simple" circuits around.

I can also vary the base voltage and control the amount of current through the LED or other load devices. However, for some loads, even this circuit might be an improvement over a simple resistor.

Most circuits that require current loss detection use expensive isolation amplifiers. This circuit solves that problem with a simple and low-cost method to detect current loss of 4-20 mA.

Two process control signaling schemes were to be supported — the 0 to 10 VDC analog signal, and the venerable 4-20 mA current loop.

A simple circuit uses one control device to control bass and treble simultaneously, with a symmetric response that is flat at the center of the adjustment range.

Short circuit current ratings should not be overlooked during panel design. Negative impacts can occur to production, equipment and, worst case, plant personnel.
