You should connect the negative cable to the negative. Your question sort of stopped. Connect to a negative what?
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...
DC means "direct current." Normally this is provided by a battery or transformer. Positive - The positive contact where current flows into a circuit. Neutral - The ground wire in case something happens like a surge. Negative - The negative contact where current leaves.
It leaks
Lightning strikes by trying to earth it's current. It's made by positive and negative ions. An example would be a battery. Let's say you were changing the battery for a toy car and you electrocute yourself. It happens by traveling down your body to the ground. Lightning acts the same but it's a higher voltage
When you submerge the glass, oxygen bubbles form on the positive outlet, and Hydrogen bubbles form on the negative outlet. Soon a mould sort of thing starts to form on the water. Try it out, it is an awesome experiment. PS- All this stuff only happens if you place 1/2 a teaspoon of slat in the glass and stir it in, the submerge the battery. PSS- Make sure the whole battery is submerged.
Nothing as long as you did not then connect the other cable.
Voltmeter will give you opposite readings or will not work at all.
Very Dangerous........it would be a dead short. andcouldcause a fire or explosion.
What happens when you inadvertently crossed the positive battery terminal from a negative to a positive and a positive to a negative.?Read more: What_happens_when_you_inadvertanly_crossed_the_positive_battery_terminal_from_a_negative_to_a_positive_and_a_positive_to_a_negative.
Voltage Options using Two 12 Volt BatteriesEach 12 volt battery HAS 12 volts in a stand-alone configuration.If you want to "get" 12 volts and yet use both 12 volt batteries, then you hook them up in a "parallel" fashion.Parallel connection means that a cable is used to connect the positive [+] terminal of one battery to the positive terminal of a second battery. And another cable is used to connect the negative [-] terminal of first battery to the negative terminal of the second battery. This configuration provides the same 12 volts, but allows greater current [Amps] to be available.Another configuration ["series" connection] will create a 24 volt battery from the two 12 volt batteries.Series connection involves the use of only one cable to connect the positive terminal of one battery to the negative terminal of the second battery.NOTE: it is CRITICAL that you NEVER connect a cable or wire between the positive and negative terminals of the same battery, or series of batteries. IF this happens, a condition called a 'short circuit" occurs, and WILL result in gigantic sparks [arcing], much heat, and the very distinct possibility that the the battery will explode in your face!!!!!
once a battery is connected even if the key is not in the ignition, there is always power at certain points in your car. Connecting a battery backwards will not start your car, but it can and will fry the wires to your starter.
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.
It could cause the battery to explode. It can also destroy some of the electronics in the vehicle. In other words this would be a very expensive mistake.
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.
your battery will make a big spark or your battery could blow up.
Depending on the age of the vehicle you probably have shorted or grounded the electrical system causing fuse(s) to blow. Question was kind of broad may want to be more specific
If you connect positive to positive and negative to negative you will have a 9V battery with twice the current capacity in milliampere hrs than a single batteries. The load then goes between positive and negative paralleled terminals. If you connect one negative of one battery to one positive of the other battery and put the load between the remaining negative and positive terminals you have created an 18 V battery with the same milliampere hr rating as a single battery. If you connect one negative to positive of other battery and the negative of that battery to the positive of the first battery then both batteries with quickly drain and get hot in the process. Contrary to folklore or urban lefends, they do not explode.
