Electrons are negatively-charged particles that flow out from the negative terminal and into the positive terminal of a battery. It was once assumed that moving particles had a positivecharge, and so this conventional current flow set the original arrow direction, still shown on diodes and junction transistors.

There is a purely arbitrary convention that the charge on the electron is negative, and the charge on the proton is positive. All we really know is that the charges are opposite; they are not really negative and positive in any fundamental sense. So, a terminal from which negatively charged electrons come, would also be considered to be negative.

Electrons, which are negatively-charged particles flow from the negative terminal to the positive terminal. This is contrary to popular belief but is none the less the way electrons flow.

electrons come from the negative terminal, then goes around the complete circuit (clockwise) and comes back to the positive terminal. hope that helps!


If a proton is negative and a neutron is positive when they come together equally how can there be positive and negative atoms?

Loss or gain of electrons.


Where does the electricity come out of a battery?

The electricity flows out the negative terminal, through the work load, and back into the positive terminal. It consists of negative electrons. In the early days of electrical experimenting, the scientists had to guess as to whether the electric flow was positive particles or negative particles. They had no way to test. They guessed positive. They were wrong. So we have inherited a definition of current as positive fluid going from positive terminal (outside the battery now) to negative terminal. We have stayed with that convention even though we know better today. It makes no difference at the circuit level. Positive particles flowing rightward has the same effect as negative particles flowing leftward. Of course, if you are designing batteries, you will want to know what flows which way.

If it's a pregnancy test the answer is no, A test can come back negative even though its positive. But if it's positive, it's positive 99% of the time.


A battery has a difference in potential energy between the positive terminal and negative terminal which units express the difference?

Volts. Volts is another term for potential.


How do rechargeable batteries work?

Click the link below A rechargeable battery is also known as an accumulator. It uses one or more electrochemical cells. During the charging process the cathode end which is the positive has negative electrons pushed through it mixing in the small chamber of the battery. The anode has positive electrons come in. The positive and negative electrons are combined and mixed inside and are released from metal to metal contact and are then used as electricity.

How do positive and negative neutrons form?

They don't. A neutron is neutral; it doesn't come in positive and negative versions.


How do you remove the battery out of a 1992 lumina?

Start by locating the Positive terminal (usually the red one)... Disconnect it from the battery. Then do the same for the Negative terminal (the black one). Then there may be a small hex head bolt at the bottom the the battery, check for it and remove it, the battery should come right out.
