Answer: As the potential difference between the two terminals of the battery is equal to the work done in moving a unit charge from one terminal to the other. Potential difference V = W/Q = 100 J/20 C = 5 V.

With battery terminals, the negative terminal has a tiny, tiny excess of electrons. The positive terminal has a tiny, tiny excess of positive metal ions.

Hence the Potential difference flowing between the terminals of a battery when 250J of work is done to move a charge of 20C is 12.5V.

Formula. Therefore, the energy is given to each coulomb of charge passing through a 6 v battery is 6 J.

Answer. So 12 J energy is transferred by a 12 V power supply to each coulomb of charge which it move around a circuit .

Then we can see in this example that every coulomb of charge possesses an energy of 9 joules.

How much energy is given to each coulomb of charge that flows through a 1.5-volt battery? 1.5 Joules.

Electrostatics

Term. Meaning. Law of conservation of charge. Charge is neither created nor destroyed, it can only be transferred from one system to another.

Quantization of charge means that when we say something has a given charge, we mean that that is how many times the charge of a single electron it has. Because all charges are associated with a whole electron, this is possible. So electrons have a a negative charge, negative charge.

Charges are quantized because the charge of any object (ion, molecule, etc.) Charge quantization, then, means that charge cannot take any arbitrary values, but only values that are integral multiples of the fundamental charge (charge of proton/electron).

transitive verb. 1 : to subdivide (something, such as energy) into small but measurable increments. 2 : to calculate or express in terms of quantum mechanics.

Charge is of two types, mass is only of one kind. There are two types of forces (attraction and repulsion) between charges, but there is only one kind (attraction) between masses. Charge has SI unit coulomb, the SI unit of mass is kg. Charge is conserved, but mass alone is not conserved (Mass + Energy is conserved).

Mass and charge both are fundamental and do not have a definition. Both exert force on like bodies(i.e., mass exert force on mass (gravitational force) and charge exert force on charge(electrostatic force)). Gravitational force and electrostatic force both varies inversely with second power of distance between them.

The attractive force between the electrons and the nucleus is called the electric force. This implies that the electric force does not depend on the mass of the particle. Instead, it depends on a new quantity: the electric charge. The unit of electric charge q is the Coulomb (C).

Electrical charge does not exist without mass, in fact, it might be called a property of mass which in itself is a form of energy, as discovered by Einstein. In Quantum Mechanics mass is described both in the form of wave equations and as point particles where the energy content is concentrated to a mathematical point.

The statement that “a charge can exist without mass” is false. This is because none of the fundamental particles that form the Standard Model have charge without mass. The Standard Model describes all energy and matter that makes up the universe, except gravitation. And gravitation does not have charge, it has mass.

A charge differ from the mass because: Electric charge is always conserved but mass may not be conserved as it can be converted into energy. Charge cannot exist without mass but mass can exist without charge.

Mass and charge. Picture 2.1 A model of the atom with electrons on the edge and a central nucleus made of protons and neutrons. Atoms have a tiny central nucleus with electrons whizzing around outside it. The electrons are fundamental particles….

Electrons

Electrons belong to the first generation of the lepton particle family, and are generally thought to be elementary particles because they have no known components or substructure. The electron has a mass that is approximately 1/1836 that of the proton.

The Higgs field gives mass to fundamental particles—the electrons, quarks and other building blocks that cannot be broken into smaller parts. The energy of this interaction between quarks and gluons is what gives protons and neutrons their mass. Keep in mind Einstein’s famous E=mc2, which equates energy and mass.

All of the atom’s mass comes from its nucleus, but all of its size comes from the fact that the electron refuses to get too close to the proton.

Electrons are much smaller in mass than protons, weighing only 9.11 × 10-28 grams, or about 1/1800 of an atomic mass unit. Therefore, they do not contribute much to an element’s overall atomic mass. Protons, neutrons, and electrons: Both protons and neutrons have a mass of 1 amu and are found in the nucleus.

All atoms have at least one proton in their core, and the number of protons determines which kind of element an atom is. Electrons are usually depicted in drawings as much smaller than protons or neutrons because their mass is so much smaller. In fact, electron mass is so small that it is not counted in an atom’s mass.
