Dumbest cable question

Fuses are certainly NOT directional...turn a fuse around in in a decent system and then just sit there and reflect on the fact that you have too much free time.

Cables and fuses are directional because they have a hot end and a cold end.

This is similar to the Sun, which has a hot side and a cold side and this causes winter and summer as the Earth circles around it.

That isn't the dumbest question but it sure is the dumbest answer.

The seasons are not caused by the sun being colder on one side than the other.

They are caused by the tilt of that axis of the earth at about 22º which causes the intensity of the sun's rays, which are parallel, to b spread over greater or lesser areas of the earth's surface, resulting in absorption of less or more energy.  Try the old school experiment of shining a torch vertically over a flat surface and then at an angle.  The illuminated area is larger from an angle, spreading the given amount of light over a larger area.

@clearthinker ,

thanks and let there be light!

is there an emoji for irony?
