When it comes to electrical circuits, there’s a lot to remember and understand. We've got you covered with this Intro to Circuits BBC Bitesize guide.

The 4-20 mA transmitters used in industrial current-control loops can be implemented as powered current sources, remote non-powered current sinks, or with several other I/O combinations. A useful ...

Basic LM317 current source I wondered if the subcircuit consisting of the LM317 and resistors Rs and Rc could form the basis for such a circuit if it were driven from a suitable control current. In ...

CMOS current reference circuits play a critical role in modern integrated circuits by providing a stable and reproducible current source that remains unaffected by variations in supply voltage ...

A monolithic current source uses two external resistors to program its output from 0.5 mA to 200 mA with 1% initial accuracy and a low temperature coefficient.

The op-amp circuit in question. He starts with the current source, a simple circuit of two diodes, a resistor, and a transistor that sets the bias for the two-transistor differential amplifier.

The difference between static discharge and continuous current is explained. Introduction to Electric Current: The difference between static discharge and continuous current is explained. Sources ...

At first glance, [RobBest]’s constant current source looks old school. The box is somewhat old-fashioned, featuring switches and binding posts. Most importantly, there’s a large analog meter ...

The conventional solutions employ concepts based on tone generation/reflection or current-source circuits. This may prove to be costly, particularly in low-cost applications like automotive designs.
