It goes without saying that the Emus will retake Australia.

Since they’re flightless, the rest of the world will be safe for a while. But when they form a navy or invent air travel, the rest of the world better watch out!

Edit: LOL, I just noticed your instance. You know what I’m talking about. 😛

The longer the distance, the larger the diameter of the wire you need, due to resistance/heat.

Typically, extension cords are going to be manufactured with the thinnest wire they can get away with based on the safety requirements, in order to save on materials cost.

So plugging 2 short cords together might cover the same distance as 1 longer cord, but the longer cord will use thicker wire to maintain the proper margin of safety.
