Dipole moment

Clearly dipole moment has the unit Coulomb meter (Cm) in S.I. unit of electric field is N/C i.e newton per coulomb.

Electric Charge

Electric charge is the physical quantity whose SI unit is Coulomb. It is a fundamental property of matter that gives rise to electric forces and interactions. Electric charge can be positive or negative, and like charges repel each other while opposite charges attract each other.

SI unit of Electric Charge

The SI unit of electric charge is the Coulomb (C). It is named after the French physicist Charles-Augustin de Coulomb, who made significant contributions to the understanding of electric forces. One Coulomb is defined as the charge transported in one second by a constant current of one Ampere (A).

Explanation

Electric charge is a fundamental property of elementary particles such as protons and electrons. Protons have a positive charge of +1.6 x 10^-19 Coulombs, while electrons have a negative charge of -1.6 x 10^-19 Coulombs. The charge of an object is determined by the number of protons and electrons it possesses.

When charges are at rest, they create an electric field around them. The interaction between charges is governed by Coulomb's law, which states that the force between two charges is directly proportional to the product of their magnitudes and inversely proportional to the square of the distance between them. Mathematically, it can be expressed as:

F = k * (q1 * q2) / r^2

Where F is the electric force between the charges, q1 and q2 are the magnitudes of the charges, r is the distance between them, and k is the electrostatic constant.

Electric charge plays a crucial role in various phenomena, such as the flow of current in conductors, the behavior of electric fields, and the generation of electrical energy. It is the basis of many technological applications, including electronics, telecommunications, and power generation.

In conclusion, electric charge is the physical quantity measured in Coulombs. It is a fundamental property of matter and is essential for understanding and analyzing electric phenomena.
