Can you install a diode to allow 24 volts AC to flow in one direction but not allow the flow of 24 volts AC to flow in the opposite direction?
The term "conventional flow" is usually used specifically for electricity, not for any kind of energy. If the current consists of electrons, then, if the electrons move in one direction, the conventional flow (a ficticious flow of positive charge) flows in the opposite direction. If the electric flow consists of positive charges, then the conventional flow and the physical, or real, flow, are in the same direction. An electron current is the most common case…
Positive electrical flow is electrons flowing in one direction in a wire, if they change the direction of flow that would be a negative flow. If they change direction quickly, say 60 times a second, that would be alternating current, which is what we have in the united states as household electricity.
