What is a current source?
1 Answer
As of my last update in September 2021, a current source is an electronic circuit or device that provides a constant, predetermined electric current to a load or a circuit. Unlike a voltage source, which maintains a fixed voltage across its terminals regardless of the connected load, a current source ensures a steady current flowing through the load, adjusting the voltage as needed to maintain that constant current.
Current sources find applications in various fields, including electronics, electrical engineering, and physics. They are used in circuits where a stable and known current is required, such as biasing circuits, sensor interfaces, LED drivers, and certain types of amplifiers.
It's important to note that technology and terminology can evolve over time, so it's possible that new developments related to current sources may have emerged since my last update. I recommend consulting more recent sources for the latest information.
