What is the true definition of electric charge?

In summary, charge is a measure of the electrical participation of matter and is not defined but rather measured through experiments. It can be compared to other materials based on this property. In Gaussian units, charge is defined in terms of mass, length, and time with specific units.

Wiki article:

an alternative (not yet official) definition of the coulomb. A coulomb is then equal to exactly 6.24150962915265 × 10^18 elementary charges.

Hi.
Force by electric field / electric field.
Regards.

Charge is the measure of electrical participation of matter. A particle with 0 charge does not interact directly in electrical events.

What is the actual definition of mass? What is the actual definition of temperature?

All three represent properties of materials. The origin of the properties is not known, but it is possible to measure and compare different materials based on those three (and most likely other) properties.

Elementary charge is measured (implicitly through experiments), not defined.

Fwiw, recently another member here, clem, pointed out that in Gaussian units, charge is actually defined in terms of mass, length and time, and has units of mass(in grams)^1/2 x length (in cm)^3/2 x time (in seconds)^-1.
 

1. What is the scientific definition of charge?

The scientific definition of charge is a fundamental physical property of matter that causes it to experience a force when placed in an electromagnetic field. It is measured in coulombs and can be either positive or negative.

2. How is charge different from electricity?

Charge and electricity are closely related concepts, but they are not the same thing. Charge is a property of matter, while electricity refers to the flow of charged particles or the presence of an electric field.

3. What are the two types of charge?

The two types of charge are positive and negative. Positive charge is associated with protons, while negative charge is associated with electrons. These charges can attract or repel each other, depending on their polarity.

4. How is charge conserved in a closed system?

In a closed system, the total amount of charge remains constant. This means that charges cannot be created or destroyed, but can be transferred from one object to another. This is known as the law of conservation of charge.

5. What is the relationship between charge and electric fields?

Charge creates an electric field around it, which exerts a force on other charged particles. The strength of the electric field is directly proportional to the amount of charge and inversely proportional to the distance from the charge. This relationship is described by Coulomb's law.
