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 ...

Download this article in PDF format. Part 1 of this series focuses on high-performance electronic loads for testing power supplies that have low output voltage and high current. It describes the ...

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 ...

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 ...

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 ...

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… ...
