This is a question Amazing displays of ignorance

Sandettie Light Vessel Automatic tells us: "My dad's friend told us there's no such thing as gravity - it's just the weight of air holding us down". Tell us of times you've been floored by abject stupidity. "Whenever I read the Daily Express" is not a valid answer.

Gah! Now I have to go and do Science!

The current isn't going to flow any "faster", as in with any more speed.
But if the electron flow is affected by gravity there should be less resistance in the cable to current in one direction.

This can easily be tested.
Get 1m of wire, apply a known DC voltage (1 volt would make ths sums easiest) and measure the current flow in various orientations.

1) Horizontal +end North
2) Horizontal +end South
3) Horizontal +end East
4) Horizontal +end West
5) Horizontal +end Up
6) Horizontal +end Down

I think you're going to need a very senstitive meter to detect any difference.

Another test might be to measure the voltage difference between the ends of a vertically held wire to see if all the electrons have sunk to the bottom...

Your last test would not work
The potential difference would be the same, but the distribution would be non linear. You would need to take the PD at various points along the wire when horizontal or vertical, to see if the distribution changed.

What do you think?

Easy.
Turn it up the other way really quickly.
