This directional behavior is analogous to the way an electronic diode facilitates unidirectional current flow based on the ..

Then the diode was known as a "valve," because it forced current in the tube to travel exclusively in one direction. Getting that single directional flow was critical for radio sets which needed ...

A diode allows current to travel in only one direction. With that in mind, [Alex] built a mechanical diode that will only allow gear rotation in one direction to be transmitted through the system.

The diode has a very high resistance in one direction. This means that current can only flow in the other direction. This is the graph of current against voltage for a diode. Normally a diode will ...
