miles long, would it still measure 9V if someone 10 miles away measured with a voltmeter?

Voltmeters have an extremely high input resistance usually 20 megaohms per volt. So the answer would be yes. Now if you had an AC source rather than a DC source like the battery then there could be some parasitic losses would reduce the voltage.

The answer is absolutely yes as long as the wire is large and remains open and no load except your measuring device (voltmeter). You just have to use a volt meter with a high input impedance to minimize the voltage drop.

You can even go further that ten miles 40 miles if you want just don't put any load.

I purely had to handle that twine,and this exchange into the only sensible thread i ought to discover everywhere. So, for what it incredibly is nicely worth: The small twine on the constructive terminal of my 'ninety two Accord has been impressive via a strand or 2 for it sluggish. It finally broke, and the motor vehicle without delay does not initiate. Solenoid click, particular. Starter motor, no. So, I stripped the twine, positioned on a sparkling crimp-on terminal, the motor vehicle began real away. I had before wiped sparkling the battery terminals and connectors, so because it incredibly is not the subject. i think of that small twine must be a relay to enable present day to the starter motor.

As long as the voltmeter had an infinite input impedance, yes

It would depend on the gauge of the wire and the load impedance of the meter.
