what are the two kinds of charges?

Answer 1

Positive and Negative

Answer 2

What is a Charge? We have a Charge in large mass structure. We also have a Charge in micromass structure.
The Micromass structures require more Gravity pressure to hold them togehter.
Since the gravity pressure is so great in micromasses when they comes to touch in very close proximity repulsion forces occur. Whereas in the Charge of macromass, repulsion forces just do not take place because the relative gravity pressure is small compared to that of micromasses.
However all charges of mass structure experience the same Gravitational phenomena.

That Means that The electrical ,and magnetic phenomena are are related to the same phenomenon which we call Gravity.
Charge is relative to the Energy per Unit mass.

In atomic structure The Electron has a Rest Charge. As the electron aproaches the Nucleus it experiences a change of velocity. A Change of Electron velocity means a change in its Charge. Hence the Charge of the electron as well as the proton is Variable. However a free electron outside the atom exibits a quasi constant charge.

See Dr. Ricardo Carezani's Equation on the Variation of charges in atomic structures.

I hope that this solves your delemma on your positive question.

Answer 3

Charge
there are two kinds of charge, positive and negative
like charges repel, unlike charges attract
positive charge comes from having more protons than electrons; negative charge comes from having more electrons than protons
charge is quantized, meaning that charge comes in integer multiples of the elementary charge e
charge is conserved
Probably everyone is familiar with the first three concepts, but what does it mean for charge to be quantized? Charge comes in multiples of an indivisible unit of charge, represented by the letter e. In other words, charge comes in multiples of the charge on the electron or the proton. These things have the same size charge, but the sign is different. A proton has a charge of +e, while an electron has a charge of -e.

Electrons and protons are not the only things that carry charge. Other particles (positrons, for example) also carry charge in multiples of the electronic charge. Those are not going to be discussed, for the most part, in this course, however.

Putting "charge is quantized" in terms of an equation, we say:

q = n e

q is the symbol used to represent charge, while n is a positive or negative integer, and e is the electronic charge, 1.60 x 10-19 Coulombs.

The Law of Conservation of Charge
The Law of conservation of charge states that the net charge of an isolated system remains constant.

If a system starts out with an equal number of positive and negative charges, there¹s nothing we can do to create an excess of one kind of charge in that system unless we bring in charge from outside the system (or remove some charge from the system). Likewise, if something starts out with a certain net charge, say +100 e, it will always have +100 e unless it is allowed to interact with something external to it.

Charge can be created and destroyed, but only in positive-negative pairs.

Answer 4

Positive and Negative

Answer 5

Positive charge (lacking electrons).
Negative charge (having a surplus of electrons).

Answer 6

It is positive and negative.
The negative charge is possessed by electrons, and the positive charge is possessed by proton.

Answer 7

I'm guessing positive and negative

Answer 8

positive and negative
