Delve into the fascinating world of resistors, a key component in nearly every electronic device we use today. Resistors are crucial for controlling the flow of electrical current in a circuit ...

Suitable for use in hazardous and non-hazardous environments, the EC-E circuit breakers selectively protect load circuits connected to a 24-Vdc power supply. The components combine active current ...

Download this article in PDF format. High-brightness visible-light LEDs (VLEDs) require a constant-current source. This simple, RFI-free circuit takes advantage of the normally-on properties of ...

The circuit uses a 9V battery and a voltage regulator to produce a steady power-supply voltage of 5V. From that voltage, the circuit produces a constant sink current, which is independent of the ...

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, but also as a constant power and ...

Circuit provides constant-current load for testing batteries Simple dual constant-current load tests low-current power supplies Prevent 9V cells from excessive drain with this battery monitor Design a ...

In [Dave’s] latest episode of the EEVblog he takes a look at constant current dummy loads. These are used to test power supply designs and instead of just chaining resistive loads together ev… ...
