Hey, I have a question! What would happen if I make a short circuit this long

[From: ] [author: ] [Date: 12-04-14] [Hit: ]
so for 10 ft, that is 0.01 ohm.but for 40000 km, that is 130000 ohms. With 1.......
Let's say that the battery is an alkaline AA cell

Will the electrons flow trough it? And will the cell get warm, as in a common short circuit?

Nothing. Any ordinary wire that long would not be a short circuit.

Don't forget that wire has resistance, although small. But for 40000 km, the resistance is very high.

Eg, #12 wire, as used in house wiring, has a resistance of 1 ohm per 1000 feet. so for 10 ft, that is 0.01 ohm.

but for 40000 km, that is 130000 ohms. With 1.5 volt cell, that is only 11µA, a small current.

easier said than done... the circuit always has a given degree od resistance to the electron flow and the longer the circuit the more resistance it will have . It is possible to make the circuit so long in fact that no current will flow...

You might get one or two electrons to jump off the battery into the wire, but it won't get hot.
