Current sources are widely used in industrial control systems to transport analog process signals over long distances, but they are less widely used than voltage sources. This post loosely reviews the ...

G1 is a voltage-controlled current source. It has a value of 6, which corresponds to a voltage of 1 V at the plus input of G1 that will provide 6 A at its output (Fig. 14).

A current source provides electrical energy with a constant current. The implication is that if the resistance of the load changes the current source will vary the voltage to compensate.

A simple extension of a previous class A/B differential output amp DI that creates a square-law characteristic.

Researchers at the US Department of Energy’s Oak Ridge National Laboratory (ORNL) say they have developed medium-voltage circuit breakers capable of handling increasing levels of DC at a lower cost.
