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 ...

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, ...

This dummy-load circuit, which is useful for testing power supplies and power amplifiers, is based on the Maxim MAX6006 voltage-reference IC and MAX480 operational amplifier. This dummy-load circuit ...

Testing power supplies and batteries requires current loads capable of sinking large current and dissipating substantial amounts of power. A simple but accurate current load can be built using just a ...

Supplying a constant current to a variable, low-resistance load, such as a thermoelectric cooler, can be a very inefficient endeavor when using the linear approach. Even powering the linear current ...

The applications and implemented volume of lithium-ion batteries have been gaining momentum each year. Aiming to contribute to the development of research in this area, this paper presents the design ...

You need to know how to investigate how current changes with voltage for a component, eg for a resistor (or wire) at constant temperature, a filament lamp and a diode. You should be familiar with the ...
