What is an ideal current source?

Question

Accepted Answer

An ideal current source is a device that provides a constant current output regardless of changes in load resistance or voltage.

An ideal current source has zero output impedance, meaning it can deliver the specified current to any load resistance without voltage drop.
It maintains a constant current output even if the load resistance changes.
Examples of ideal current sources include transistors operating in the active region and specialized current source circuits.
An ideal current source is often used in electronic circuits for biasing, testing, and calibration purposes.

Accepted Answer

In an electrical circuit, if a current source provides constant current, with maximum efficiency at any given point, it becomes an ideal source.
