[Julian] knows that real diodes you can buy don’t work exactly like we say they do. That’s actually pretty common. We routinely ignore things like wire resistance and source resistance in batteries.

This video explains how diodes function as directional components in electronic circuits. Diodes allow current to flow in ...

Researchers have demonstrated how a heterostructure consisting of superconductors and magnets can be used to create uni-directional current like that found in semiconductor diodes. A group of ...
