I like watching science videos on YouTube and I have a very basic understanding of electronics. But I never seem to get the “negative voltage” thing.
Why is it used and how does it differ from normal voltage.

Consider electricity being similar to plumbing. A closed circuit one, to be precise.
Imagine we have a pump and a curvy pipe sticking to both ends of the pump.
The pump pushes a liquid to the pipe through the output hole and expects it to get back to the pump from the other side – the input.
The pump generates a pressure at the output – that’s the “positive” pressure. And on the input you get under-pressure as the pump is sucking the liquid in. That’s the “negative” pressure.
The same thing happens in electricity. Just imagine the voltage being the pressure a pump generates.
Hope this is clear 😅
