Some projects are both educational and useful. We believe that [Jasper’s] Arduino based electronic load is one of those project. [Jasper’s] electronic load can not only act as a constant current load, ...

DC electronic loads have been available for electronic testing applications for several decades. Today’s products include switched resistors, high-speed active loads utilizing power semiconductors, ...

This dummy-load circuit has been in use at Maxim for more than 10 years (see the figure). It's useful for testing power supplies and power amplifiers as well as drivers for LEDs, relays, and solenoids ...

Many loads are mainly resistive; thus, they’re rated in watts (i.e., true power). Simply stated, these loads have a very small reactive component, which means an apparent power rating (VA) would not ...

The simplest model of a battery comprises an ideal voltage source that connects in series with a resistance whose value—often a few milliohms—depends on the battery’s electrochemical condition and ...

TE Connectivity’s latest relay product is designed to manage harsh inductive, motor and lamp loads. Intended for the requirements of rugged power switching in aerospace, defence and marine ...
