Electric charge is a scalar quantity. The electric field is a vector quantity, representing the electric force per unit charge acting on a test particle at a particular position in space. a vector quantityC. electric current does have a direction and a magnitude; however, its a scalar quantity, not a vector quantity. confused with any true, directional characteristic of electric charge, which is a scalar When two currents meet at a point the resultant current will be an algebraic sum. No,because electric field (force/charge) is a. Answer (1 of 4): Every force that has a direction and magnitude, falls under the "vector quantity" category. Talking about electric charge it fails to obey the law of vector addition even it has magnitude and direction of flow of charge . The properties can have either a direction and a magnitude or only magnitude, Any quantity with no direction but the only magnitude is a scalar quantity; the magnitude is simply a value with a corresponding unit, They have no specific direction, the scalar quantity has the same value in any direction, so they are one-dimensional parameters. It is represented as (I). Since force is a vector, the electric field too is a vector quantity. neither scalar nor vectorD. Physical quantities are vector quantities because they have a direction and a magnitude. If the quantity doesnt obey these laws, its a scalar quantity. How To Identify Positive and Negative Terminal of DC Motor? . Necessary cookies are absolutely essential for the website to function properly. Why Is Electric Current a Fundamental Quantity? why? According to scientific description, each physical property that has a piece of specific information and can be quantified and measured is called a physical quantity. The electric field is a vector quantity because it has a direction based on the particle's charge. Explanation: In the case of electric current , although it has direction, but when the two current collides or meets their sum is equal to the algebric sum and not vector sum (i.e it does not follow the parallelogram of vector addition). Other factors, however, determine if a number is a vector or a scalar. The positive sign for current corresponds to the direction a positive charge would move. Why can work be negative if it is scalar? Batteries produce direct current. Explanation: In the case of electric current , although it has direction, but when the two current collides or meets their sum is equal to the . It does not store any personal data. Nothing is a vector until defined with a direction. The current formula is given as I = V/R. Current has a direction. Scalar quantities have many other examples, such as mass, length, speed, and duration. Its SI unit is coulomb (C).

In fact, its all three; a scalar can be viewed as a one dimensional vector or a zeroth order tensor. An electric potential is the amount of work needed to move a unit of positive charge from a reference point to a specific point inside the field. Is Electric Current a Scalar or a Vector Quantity? Starting with the premise that the electric charge associated with fundamental fermions (quarks and leptons) can, under certain circumstances, be appropriately represented as a real \emph{internal} 2-vector, the mathematical ``machinery'' implicit in the associated internal 2-space is shown to apply to \emph{all} fundamental fermions. So when two scalar quantities are combined, they can be calculated through typical algebra.

Can an electric field be zero? In addition, the total current is not affected by the angle between the wires. The scalar quantities have only magnitude. Comparing electron motion to that of an elementary school child, we would see a tiny bundle of energy, bouncing off everything in a totally random trajectory. In metal wires, current is carried by negatively charged electrons, so the positive current arrow points in the opposite direction the electrons move. . When a change is applied to a vector quantity, it can affect either direction change, magnitude, or both. . So magnitude is the only thing affected by a change in the scalar quantity because they have no direction. The Question and answers have been prepared according to the Class 12 exam syllabus. By convention, the electric current direction is the direction which positive charge would move. Thus current is considered as the fundamental physical quantity and charge is a .

Vector can have one-dimensional, two-dimensional, or three-dimensional. Then, the electric current is not a vector quantity regardless that it has a direction and a magnitude. Work which is positive (+) is the result of a force which contributes energy to an object as it does work upon it. We call them scalars. Their effects exactly counteract each other. Scalar quantities have the same value regardless of their direction, so they cannot be resolved. 27727 views But we do know that electric charge can attain a magnitude of force under favorable conditions to become available as power we can use. The direction and magnitude are not the only factors determining if the quantity is a vector or a scalar. 4 Why is electric charge a scalar quantity in physics? Here Is Why, Why Electrical Insulators Dont Conduct Electricity?, How To Determine If Current Is AC or DC - 3 Steps, How To Identify a Fuse on a Circuit Board? In vector quantities, a vector quantity is the intensity of an electric field.

Other examples of scalar quantities include pressure, energy, concentration or density. The charge is a scalar quantity, but the electric force is a vector quantity, and therefore the electric field has magnitude and direction both. Due to the presence of an electric charge, a body either attracts or repels another body based on the nature of the charge. The cookies is used to store the user consent for the cookies in the category "Necessary". Henceforth, even Electric Force is a vector quantity. Hence it is a scalar quantity and is not a vector even though it has direction. To sum up,electric current does have a direction and a magnitude; however, its a scalar quantity, not a vector quantity. Hey, Im Viliam and I started this website to provide you with tips for problems that we have in our daily lives Tips focus on housing (interior, exterior, garden), but also other tips about electricity, bikes, cars, and also other stuff. Then the paths became elliptical as depicted in so many illustrations. *Due to these electric charges various object exerts strong electric forces attraction or repulsion on each other . The current can be added or divided into several components arithmetically. Another example of sub-atomic particles is atoms but not ordinary atoms, the excited atoms. Why is electric charge a scalar quantity in physics? Some common vector quantities are force, velocity, displacement, and acceleration. Vector quantities have two characteristics, a magnitude and a direction. An electric charge is a conserved quantity.
