What is a Positive

Charge? This means that in the area of the object nearest

to the positive object there is a net

negative charge, and therefore an attraction will

occur between the two

objects. Positive charge has many useful

applications. For example, charges that are

attractive are used for spray painting cars.

When a positively-charged terminal is attached

to one end of a metal wire and a negatively-

charged terminal to the other, an electric field is

generated by the charges. The electrons migrate

towards the positive charge, creating an electric

current.

What is a Negative

Charge?

In 1839, Michael Faraday identified the

existence of different polarities. He defined

one of these polarities as maintaining

a negative charge, although the distinction

between positive and negative charges was

purely arbitrary.

Ions that have more electrons than their

original elemental form carry

a negative charge, while those with fewer

electrons carry a positive charge.

The charge causes them to attract or repel

other charged particles.

What is a Neutral?

An electrical terminal or conductor which

has zero or close to zero voltage with

respect to the ground.

The number of positively charged protons

in an atoms nucleus.

Is an equal amount of positive and

negative charge to produce a neutral

charge. Just the presence of neutrons

does not make the atom neutral.
