Nothing will happen. There has to be a complete a circuit for the battery to function thus allowing for the flow of electricity.
Nothing. The reason a circuit works is that there is an imbalance between the positive and negative (cathode and anode) ends of the battery. two positive ends wouldn't move anything.
Nothing. An auto battery system is 12V DC. If both terminals aren't in the loop (positive through the current path and back to negative) nothing happens.
No, when nothing is connected, no power is used even though the circuit is live and ready.
The current depends on what is connected to the battery's terminals. If nothing is connected to it, then there is no current, and the battery lasts quite a while. In general, the current is 1.5/resistance of the external circuit connected to the battery until that number gets too big, and then the voltage of the battery sags, because it can't deliver that much current.
This could be the voltage regulator. Both the positive from the battery and the starter would be connected to it.
Nothing happens to the vehicle if you connect the negative side first.But is is safer to connect the positive side first. Reason If the negative side is already connected and you put the positive side on you take a chance of touching a part of the body or radiator with your wrench while tightening it, causing the positive side to ground out. If your negative side is not connected yet and you touch the wrench to the body while tighting the positive side nothing will happen. So installing the positive side first reduces the chance of shorting the battery out which could cause the battery to explode.
Make sure that you connected the battery cables properly. The red cable goes to the positive side(+) the negative or black cable to the (-) side.
If it's a car/motorcycle battery you will be welding! If it's a small electronics battery nothing. Volts are not really the issue here, but amps are. And yes some old cars did or do have 6 volt batteries if not converted...
Nothing, glass is an insulator.

Engine ground can find many paths to the battery, but if NOTHING is connected to the negative post... no, it won't start.
No, the battery is part of it's circuit. In fact nothing in the car will work without the battery.
