It is to be noted that the bodies which are charged bodies in a system of charges that are very small as compared to the distance which is between them are treated as point charges. Very often we deal with systems where the influence of many systems is taken into consideration. To calculate the final effect in such cases that we need to subtract and add these charges from one another.Â

To simplify the operations which are involved, it is very necessary that we study the properties of charges which are point. In this topic and section we will learn about three such point properties of charges, the electric charge additivity of the charge, the electric charge conservation and at the quantization of charge which is electric charge.

If we look at the principle of conservation of charges we can notice that the charges are neither destroyed nor created, they are transferred from one body to the other body as well. If we take an example of two objects one has some charge and the other one has no charge which are made to come in contact with each other.Â

The transfer of charge is from the object which is possessing some charge to the other object which is possessing no charge until and the charge is equally distributed over the whole system as well.Â

Here if we see so we can notice that no charge is lost or created and is only transferred from the one which is possessing an excess of charge to the other possessing.

An Electric charge can be defined as it is the physical property of matter that can experience a force when it is placed in an electromagnetic field. There are basically two types of electric charge that are negative andÂ positive that are commonly carried by electrons and protons respectively.Â

The like charges are the charges which repel each other and unlike charges are the charges which attract each other. An object that is having an absence of charges which are net is referred to as neutral charges. The very early knowledge of how the substances which are charged interact is now called classical electrodynamics and still accurate for problems which really do not require consideration of effects of quantum.

An Electric charge is said to be a conserved property, the net charge which is of an isolated system, the amount of charge which is positive charge minus the amount of charge which is negative charge cannot change. Electric charge can beÂ carried out by particles which are subatomic.Â

If there are electrons which are more than protons in a piece of matter, then it will have a negative charge for sure andÂ if there are fewer it will have a positive charge. And if there are an equal number of the charges then it will be neutral. Then it is said that the Charge is quantized.Â

It comes in multiple which areÂ integer of individual that have small units which are called the elementary charge that is e and about 1.602Ã—10âˆ’19 coulombs is its value that is considered as the smallest charge which freely exist that is the particles called quarks have smaller charges that are multiples of â…“Â e.Â

But they are only found in combination and one more point here is that they are always combined to form particles with integer charge. The proton has a charge of positive that is +e and the electron has a charge of negative which isÂ âˆ’e.

The fundamental property Charge of forms or of matter that exhibit replushion or electrostatic attraction in the presence of other matter. The electric charges which are is a characteristic property of many subatomic particles. The free standing charges of particles are integer multiples of the elementary charge that is e, we can say that electric charge value is quantized.

Scientist Michael Faraday in his electrolysis experiments was the first man to specifically note the nature of the discrete electric charge. Physicist Robert Millikan's who did the oil drop experiment demonstrated this fact directly and along with that he measured the elementary charge.Â

It has been discovered that one type of particles that are quicks and that have fractional charges of either âˆ’1/3 or +2/3Â

but. it is duly believed that they always occur in multiples of integral charge which can also be said as free-standing quarks that have never been observed.

By the process of convection we can notice that the charge of an electron is negative, that is denoted by âˆ’e, while that of a proton is positive that is denoted by +e. The particles which are Charged particles whose charges have the same sign repel one another.Â

And particles whose charges have always been different signs are the ones which attract. The law of Coulomb's quantifies the force of electrostatic which is between two particles by asserting that the force is directly proportional to the product of their charges, and that is inversely proportional to the square of the distance which is between them. The antiparticle charge is equal to that of the corresponding particle but along with opposite signs.

The SI or we can also call it as the derived unit of quantity of electric charge is the coulomb that is denoted by the symbol: C. In the particle which is of modern practice, we can observe that the phrase "amount of charge" is used instead of "quantity of charge". The symbols which are lowercase symbols that are q are often used to denote a quantity of electricity or charge. The charge of amount 1 electronÂ is an elementary charge whichÂ is defined as a fundamental constant in the SI units system.

FAQ (Frequently Asked Questions)

Q1. Mention few properties of Electricity?

Ans: The Few properties of the electric cell are as: Electricity flow of electrons through a conductor. The current amount that is in amps is related to the voltage that is volts which is pushing the electrons and the degree of resistance to flow which is ohms. During their currents flow around a circuit and the electrons can be used to create a number which is of useful byproducts such as light and heat.

Q2. Explain what an Electric Charge is?

Ans: Basic property of matter Electric of charge which is carried by some elementary particles that itself governs how the particles are affected by a magnetic or an electric field.

Q3. Mention the properties of Charge.

Ans: In answer we will learn about three such properties of point charges that are the additivity of electric charge the other one is the conservation of electric charge and the final one is the quantization of electric charge.

Q4. Mention fewÂ properties of Charge?

Ans: The few basic properties of electric charges are listed as follows

Charges are in nature additive.

Charges are the conserved quantity.

The last one is the Quantization of charge.
