Excess electric charge refers to a situation where an object has more electric charge than it normally carries in a neutral state. This can occur through the transfer of electrons between objects, leading to an imbalance of positive and negative charges. Excess electric charge can cause objects to become negatively or positively charged and can result in electrical discharge if the imbalance is not resolved.
Electric current provides a rapid movement of excess charge. It is the flow of electric charge through a conductor, such as a wire, that carries excess charge from one point to another.
The rapid movement of excess charge is known as an electric current. This flow of charge can occur in conducting materials such as metals and can be harnessed to power electrical devices.
The quantity of excess electric charge found on an object is typically measured in coulombs, which represents the total charge of electrons on the object. This excess charge can be positive or negative based on whether the object has gained or lost electrons. The SI unit for charge is the coulomb (C).
A buildup of electric charge occurs when there is an excess of electrons (negatively charged particles) on an object. This can happen when electrons are transferred from one object to another through friction or contact, resulting in a net negative or positive charge on the object.
Negative electric charge is a fundamental property of subatomic particles, indicating an excess of electrons compared to protons. It is the opposite of positive electric charge and is responsible for the attraction between particles with opposite charges.
Static Charge
Electric current provides a rapid movement of excess charge. It is the flow of electric charge through a conductor, such as a wire, that carries excess charge from one point to another.
Electric Discharge
The Earth carries a negative charge, as the electric field due to excess negative charge on the Earth points downward.
The rapid movement of excess charge is known as an electric current. This flow of charge can occur in conducting materials such as metals and can be harnessed to power electrical devices.
yes and no lmfao
A negative charge is caused by a excess of electrons and a positive charge by their lack.
In common practice, the principle reservoir for electric charge is a battery. Fuel cells, which are like batteries except with external reactant sources, are becoming more widely used as electric reservoirs. In pure circuit design, the capacitor is used as the charge reservoir.

The net static electric charge on the metal sphere would be +3 elementary charges. This means the sphere has an excess of 3 positive charges.
