What meant by one terminal of a car battery said to be connected to ground since it is not really connected to the ground?

'Ground' is an electrical term indicating the return path completing a circuit . ~ See related link below .
The negative terminal of a car battery is connected to the chassis of the car. This defines the reference point for measuring voltages in the car. It is possible for the body of the car to be connected to the ground, such as when the car is put on a metal jack. This has no electrical effect, so the body of the car is pretty much equivalent to ground.

Can you use a penny to fit full your car battery terminal?
Yes, in an emergency, but you really need to replace the worn battery cable terminal.
Do batteries give off electrons to circuits?
When any conducting material is connected to provide a continuous path between the two terminals of a battery, electric current flows through it. On the microscopic level, electric current is really the flow of electrons, from the battery's negative terminal, through the conducting path, to its positive terminal.
What does the neg battery terminal do?
A battery has two ends -- a positive terminal (cathode) and a negative terminal (anode). If you connect the two terminals with wire, a circuit is formed. Electrons will flow through the wire and a current of electricity is produced. Inside the battery, a reaction between chemicals take place. But the reaction takes place only if there is a flow of electrons. Batteries can be stored for a long time and still work because the chemical process doesn't start until the electrons flow from the negative to the positive terminals through a circuit. we take some pairs of the Cohomer Battery Terminals to test and check the result, and you can also browse the Chomer dot com website, to choose the right battery terminals to test for yourself.Electrons are negatively charged, so they will be attracted to the positive end of a battery and repelled by the negative end. When the battery is hooked up to a device that lets the electrons flow through it, they flow from negative (anode) to positive (cathode) terminal.The whole point of a battery is to maintain a voltage (electric potential) difference between two points (i.e. the positive and negative terminals of the battery). Voltage is a strictly relative quantity. The only thing that matters in the real world is voltage differences. Usually we will pick some point to define as 0 Volts (also known as ground) so that we can pretend absolute voltages exist: if some point is 10 Volts above ground, we just say it is at 10 Volts.If you have a 9 Volt battery, for instance, there is no specified reference voltage (ground). The 9 Volts refers to the voltage difference between the “positive terminal” and the “negative terminal.” If we define the potential of the negative terminal to be ground (or connect the negative terminal at a point in a circuit we have already specified as ground), we could simply call the positive terminal the 9 Volt terminal. We could easily define our reference voltage such that the “negative” terminal is really the “more negative” terminal, and the “positive” terminal is really the “less negative” terminal, but this wouldn’t be particularly helpful.A battery allows us to maintain some constant voltage between it’s terminals. Since (conventional) current flows from higher voltage to lower voltage in a circuit, if we connect a circuit across the terminals, current will flow. This is the function of battery. A battery where both terminals are at the same voltage is know as a completely dead battery.
What if accidentally Switched positive and negative battery cable?
Nothing really, i am an Graduate student with a degree in electrical engineering. The negative terminals are only grounds, if a voltage is sent to a ground, nothing happens, the electric current just disperses into ground, which is normally a metal that has no voltage. The positive terminal connected to a the negative terminal on a battery has no voltage what so ever, so nothing will happen your fine, but you will not get any power though, that's the only thing that happens, if anything you might melt a fuse if it has one, but that's it. I disagree, if you hooked both up backwards. You may have "popped" fuses, melted wires or even "fried" computers.
What happens if you don't unhook battery terminal when you remove the radio in a 2009 corolla?
You could accidentally short out the power wire to the radio and blow a fuse. But you really do not have to disconnect the battery terminal. Just remove the fuse for the radio circuit and you will be fine.
What is a side terminal battery wrench?
It is a 5/16" or 8mm wrench. There is no really set wrench for a side terminal battery as long as the wrench makes full contact with the head of the bolt. Many parts stores offer a ratcheting wrench as a side terminal battery wrench, which is essentially nothing more than a 5/16"-8mm wrench that ratchets for tight spaces
Where does the white wire connect on a six volt battery?
You don't say what you are connecting to the battery. If you have a black and white wire the best guess would be white to negative terminal and black to positive terminal. If you were connecting a 6V light bulb it really doesn't matter.
Why doent my battery charge ive tryed changing the altonator and battery?
sometimes this can be caused by bad ground cables, it will do some really weird stuff to a car if the ground is bad, it could be that the ground is rusty or dirty.
When you connected the battery cables wires began to smoke on the starter What next?
U really should know that grill
Why would your Samsung cell phone display Battery Not Connected when it is?
Maybe at the plug you did not switch it on =] If not I don't really know =]
How do you check the polarity of a electret microphone?
Usually, the negative terminal is internally connected to the microphone's metal shell. Use a tester to measure resistivity between each terminal and the outer shell; if you get zero, you found your "negative". Unless you're into some precise signal processing or some other hi-fi application, polarity doesn't really matter at the microphone.
Is possible to short out the alternator while working on car?
The alternator really can be shorted out but you can cause a short if you contact the hot battery connection to ground. whenever you work on a car, you should really disconnect the negative battery cable. It takes that battery out of harms way and you too.
