Hi
I was wondering what a dependent power supply, either voltage or current, looks like. I have seen a 'general' power supply in the lab (see link #2). Actually I was looking at the example problem 1.7 in the given link #1. It has a dependent current which is rated 0.2I. When I is 5A, the current supply by the dependent source is 1A. But how does it sense that the current supplied by the "independent" source on the left is 5A. There should be some way; I don't think it works using telepathic means!
Please help me. Thanks a lot.
