You get it. Pushing AMPs is just a voltage significantly higher than the voltage required to jump a gap, or short a circuit, ect. Depending on your application. I like to think of it as a water slide, the source is the high end, the circuit is the slid, and the sink is the bottom of the slide and pushing AMPs is attaching a comic book villan's version of a pump big enough to drain all the water from the ocean.
