Active Current Source

00:30:56

A current source supplies the same current no matter the load resistance. Notice in this circuit how the current through the blue resistor does not change as you alter its resistance! That's the magic of op amps!

The magic would be perfect if you swap the inputs of opamp +-

Ppl says that op amps sourcing magic looks good only on paper. A last placeholder in queue of things to use as source of curents just play with them a lil u see how flexible and easy to implement they are and how high quality factor can be achieved comparing to other analog compound devices for example all generation current conveyors or translinear current amps such as gain having wilson mirrors etc,etc
