No electric charges may be positive or negative - electrons have a negative charge; ions have a positive charge.
Electrons do not flow, but they might be though of as 'flowing' as they transfer charges between them. The reason that electron flow is the opposite direction from current is that historical theories of electrical flow (current) treated it as a movement of positive charges rather than negative charges.There is no actual difference that could be discerned, except that we now know that negative charges (electrons) constitute the basis of most common electricity.
Positive and negative are just directions. In AC the current changes direction 60 times a second. It is all the same.
No. There are 3 parts in the atom, which are: Proton-Positive charge Electron-Negitive charge Neutron-Neutral/No charge So protons are what carry the positive charge, where as neutrons dont carry any charge.
when a negative and a positive charges attract. or when there is a closed circuit.
Electrons are negatively charged particles. The reason the negative side of your D battery is negative is because that's where the free electrons are. The positive terminal is starved or has a deficit of electrons. The negatively charged electrons naturally want to fill the 'holes', in atoms lacking an electron on the positive side. Thus electron flow is from negative to positive. Conventional current flow assumes that current flows out of the positive terminal, through the circuit and into the negative terminal of the source. This was the convention chosen during the discovery of electricity. They were wrong!
That is the electric energy. It is called the electricity
False. 1. Electricity involves the movement of electrical charges. The most common case is the movement of electrons (a negative charge), but other possibilities exist, such as movement of charges through ions (positive or negative), or holes (positive). 2. Even stating that electricity IS a flow of charged particles is a gross and misleading simplification. An electrical current INVOLVES the flow of charges, but that does not fully describe an electrical current.
static electricity there is no flow of electrons and it is a result of imbalance of positive and negative charges only.while dynamic electricity , the flow of electrons can be either in a single direction(direct current),or it can be changing directions repeteadly (alternating current)..!
Static electricity is the BUILT UP STORE of electron charges [e-] between a pair of objects, while current electricity is the FLOW of electrons between these objects. Static electricity is a transfer of charge from one static body to another, resulting in an imbalance in positive and negative charges, while electric current is the flow of electrons, from one static body to another.
An electric current flows from negative to positive.

Conventional current flow is the flow of positive charges, or the equivalent flow of positive charges. That is, if what flows is really negative charges (for example, an electron), which flow in one direction, the "conventional current" flows in the opposite direction.
Positive and negative are just directions. In AC the current changes direction 60 times a second. It is all the same.
Electrons are a negative charge. Using conventional notation current flows from positive to negative poles of a battery, for example. In electron flow convention the electrons flow from negative to positive.

Current means flow. Electric current means flow of electric charges Now there are two kind of charges. They are positive and negative But current is defined as the flow of positive charges But in metallic wires there is no chance for positive charges to flow through. Only loosely bound electrons with negative charge are capable of flowing. So current is case of metallic wire is due to electrons. So we have to assign as "conventional current". Conventional current is always opposite to the flow of electron flow Now from a battery current (conventional) flows right from positive polarity to the negative polarity. But within batter is has to flow right from negative to positive so as to complete the circuit of flow.
