Suppose that you need to test a 1.5V, AA-size alkaline battery. You can apply a short circuit and measure current, or you can measure open-circuit voltage, but neither method properly tests the ...

FET constant current sources use JFETs and MOSFETs to deliver a load current, which remains constant despite changes in load resistance or supply voltage. A FET constant current source is a type of ...

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 ...

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, ...
