Key Terminologies Related to Electric Field
Now, let us see some of the important terminologies related to electric field that will be discussed further in the article:
- Electric Charge: An electric charge is a property of matter that causes two objects to repel or attract. It can be either negative or positive.
- Point charge: When discussing a body considerably smaller than the distance being considered, we disregard its size and refer to it as a point charge.
- Coulomb’s Law: Coulomb’s law states that the force between two point charges is directly proportional to the magnitudes of the charges and inversely proportional to the distance between the two charges.
- Mathematically : F = (k|q1q2|)/r2 ,where q1=first point charge ,q2 = second point charge.
- k = 8.988 * 109 Nm2/C2 is Coulomb’s constant, r = the distance between two point charges.
- Gauss’s law : Gauss’s law states that the net flux of an electric field in a closed surface is directly proportional to the enclosed electric charge.( further discussed in detail in the article).
- Electric flux: Electric flux is defined as the total number of electric field lines passing through a specified area within a unit of time.
Electric Field
Electric field is a fundamental concept in physics, defining the influence that electric charges exert on their surroundings. This field has both direction and magnitude. It guides the movement of charged entities, impacting everything from the spark of static electricity to the functionality of electronic devices Understanding electric fields will help you to understand how charge particles interact with each other and the surroundings and guide various natural and technological phenomena. In this article, we will learn in detail about electric field, its formula, calculation of electric field for ring, straight wire and continuous charge distribution.
