**Electric Charge Definition**

“Electric Charge is the property of subatomic particles that makes it experience power when put in an electric and attractive field.”

- Electric charge is the fundamental actual property of issue that makes it experience power when kept in an electric or attractive field.
- An electric accuse is related to an electric field and the moving electric charge produces an attractive field.
- The blend of electric and attractive fields is known as the
**electromagnetic field.** - Communication of the charges produces an electromagnetic power which is the underpinning of Physics.
- Electric charge is an essential property of electrons, protons and other subatomic particles.
- Electrons are adversely charged while protons are decidedly charged. Things that are contrarily charged and things that are emphatically charged pull on (draw in) one another.

The two sorts of electric charges are: Positive and Negative, regularly conveyed by charge transporters protons and electrons. Instances of the sorts of charges are subatomic particles or the particles of issue:

- protons are emphatically charged
- electrons are adversely charged
- neutrons have zero charge

The meaning of electric charge is given as follows:

**Is Electric Charge a Vector Quantity?**

Electric charge is a scalar amount. Aside from having greatness and course, an amount to be named a vector ought to likewise submit to the laws of vector expansion, like triangle law of vector expansion and parallelogram law of vector expansion; really at that time, the amount is supposed to be a vector amount. At the point when two flows meet at an intersection on account of an electric flow, the resultant flow of these will be an arithmetical aggregate and not the vector total. Consequently, an electric flow is a scalar amount, despite the fact that it has extent and course.

**Estimating Electric charge**

- Coloumb is the unit of electric charge.
- “One coulomb is the amount of charge moved in one moment.”
- Numerically, the meaning of a column is addressed as Q = I.t
- In this situation, Q is the electric charge, I is the electric flow and t is the time.

Electric Charge is the property of subatomic particles that makes them experience power when set in an electromagnetic field.

**Different properties of charge incorporate the accompanying:**

- Additivity of Electric Charge
- Protection of Electric Charge
- Quantization of Electric Charge

In a disengaged framework, Electric charge is preserved, and that implies the net electric charge of the framework is consistent. The arithmetical amount of the crucial charges in any detached framework continues as before.

**Two sorts of electric charges are there**

- positive(+) charge
- negative(- ) charge

**Negative Charge**

Whenever an item has a negative charge it implies that it has a bigger number of electrons than protons.

**Positive Charge**

Whenever an article has a positive charge it implies that it has a bigger number of protons than electrons.

Whenever there is an indistinguishable number of positive and negative charges, the negative and positive charges would offset one another and the item would become impartial.

**Coulomb’s Law**

We could definitely realize that like charges repulse one another and dissimilar to charges draw in one another. Be that as it may, have you required a moment to consider how solid are these powers? Coulomb’s Law gives a way to work out the strength of the power between two places.

Coulomb’s Law expresses that

The extent of the electrostatic power of fascination or aversion between two point charges is straightforwardly corresponding to the result of the sizes of charges and contrarily relative to the square of the distance between them.

**Strategies for Charging**

The method involved with providing the electric charge to an article or losing the electric charge from an item is called charging.

An uncharged item can be charged in three distinct ways as follows:

- Charging by contact ( triboelectric charging)
- Charging by conduction
- Charging by enlistment

**Charging by Friction**

Whenever two articles are scoured against one another, a charge move happens. One of the items loses electrons while the other article acquires electrons. The item that loses electrons turns out to be emphatically charged and the article that acquires electrons turns out to be adversely charged. Both the items get charged because of rubbing and this strategy for charging is normally known as zap by grinding.

**Charging by Conduction**

The technique for charging an uncharged article by bringing it near a charged item is known as charging by conduction. The charged guide has an inconsistent number of protons and electrons, henceforth when an uncharged guide is brought close to it, it releases electrons to settle itself.

**Charging by Induction**

The most common way of charging an uncharged guide by bringing it close to a charged guide with no actual contact is known as charging by enlistment.

**Dimensional Formula of Electric Charge**

The formula(dimensional ) of electric charge is [M^{0 }L^{0} T^{1 }I^{1}]

Where,

- M = Mass
- I = Current
- L = Length
- T = Time

Electric charge, q, is its own dimension. The electron has a fixed and defined charge which, if we wish, we can put equal to 1, in which case the charge reflects the number of electrons involved. It is independent of mass, length and time. You cannot manipulate any other dimension and create a charge.

**Derivation**

Electric charge (Q) = current(i) . (t)time . . . . (1)

The formula(dimensional) of,

Current(i) = [I^{1}] . . . . (2)

Time(t) = [T^{1}] . . . . (3)

From (1), (2) and (3) we get,

we know that, electric charge = current(i) . (t) time

so, Q = [T^{1 }I^{1}]

Therefore, the electric charge is represented(dimensionally) as **[M ^{0 }L^{0} T^{1 }I^{1}].**

**FAQs**

##### How are electric charges disseminated inside the molecule?

Subatomic particles convey electric charges. Electrons convey the negative charge and protons convey the positive charge in the cores of iotas.

##### For what reason is an electric charge a scalar amount?

Whenever two flows meet at an intersection, the resultant current of these will be a mathematical aggregate and not the vector total. Consequently, an electric flow is a scalar amount.
