Re: Constant current load for testing power supplies (guidelines)
That is the Voltage follower circuit. not Constant Current SOURCE that AUTOMATICALLY maintain the output current to be constant with the variable load, the key word is 'CURRENT SOURCE'

If you add zener to the circuit then it become Voltage regulator.
