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.

JudyThere 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.

A battery has a difference in potential energy between the positive terminal and negative terminal which units express the difference?
The difference in potential energy between the positive and negative terminals of a battery is expressed in volts.
When one positive charge and one negative charge come into contact what happens?
When a positive charge and a negative charge come into contact, they will attract each other due to their opposite charges. This attraction can lead to the exchange of electrons between the two charges, resulting in neutralization.
How can you get positive and negative electricity go together?
Positive and negative electricity can come together through the process of electrical neutralization, which involves the transfer of electrons between the positive and negative charges until they reach a balanced state. This can occur through the interaction of positively and negatively charged particles, resulting in a state of overall neutrality.
Does a neutral atom have the same protons and electrons?
Not necessarily. The number of protons must always equal the number of electrons in a neutral atom, but the neutron number can vary, depending on the isotope of the element in question. This is because the neutron carries zero charge, so it des not matter if there is a different number of neutrons.
What is a charged particle?
A charged particle is an atom or molecule that has an unequal number of protons and electrons, resulting in a positive or negative electric charge. These particles can interact with electric and magnetic fields due to their charge, influencing their movement and behavior. Examples of charged particles include electrons, protons, and ions.
