Electronic load using Op-Amp IC 358

Electronic load using Op-Amp IC 358

In this circuit i using IC 358 and some few components to make a simple constant load. 

The trick here is connecting a dc voltmeter to the non-inverting input of the op-amp to preset the current before connect it to the battery or the super cap. under test.

For more explanation you can watch the video below.
