Explanation: Electric field is a region around a wire carrying an electron current in which a compass needle experiences a force.
What is electric field explain?
electric field, an electric property associated with each point in space when charge is present in any form. … The strength of an electric field E at any point may be defined as the electric, or Coulomb, force F exerted per unit positive electric charge q at that point, or simply E = F/q.
What is electric field by Topper?
a region in which an electric charge experiences a force.
What is electric field Class 12?
Electric field is a force produced by a charge near its surroundings. This force is exerted on other charges when brought in the vicinity of this field. SI unit of electric field is N/C (Force/Charge).
What is electric field class 10th?
Hint: In this question use the definition of electric field which states that it is the region around a charged particle or object within which another charged particle will experience a force over it, this force can be either a force of attraction or a force of repulsion.
What is electric field in Brainly?
Electric Field: An electric field is the physical field that surrounds each electric charge and exerts a force on all other charges in the field, either attracting or repelling them. Electric fields originate from electric charges, or from time-varying magnetic fields. Unit: Voltm−1(Vm−1)
What is electric field in chemistry?
In atomic physics and chemistry, for instance, the electric field is the attractive force holding the atomic nucleus and electrons together in atoms. It is also the force responsible for chemical bonding between atoms that result in molecules.
What are electric field lines give there properties?
Electric field lines never intersect. In an uniform electric field, the field lines are straight, parallel and uniformly spaced. The electric field lines can never form closed loops, as line can never start and end on the same charge. These field lines always flow from higher potential to lower potential.
What is an electric field and how is it created?
The space surrounding a charged object is affected by the presence of the charge; an electric field is established in that space. A charged object creates an electric field – an alteration of the space or field in the region that surrounds it. Other charges in that field would feel the unusual alteration of the space.
Why do electric field lines come from positive charge?
Electric field line is supposed to be the trajectory of a “test charge” (a unit positive charge) in a given electric field. Since like charges repel each other, the test charge will move away from the positive charge, so the field lines move away from a positive charge.
What is electric field Byjus?
Electric field can be considered as an electric property associated with each point in the space where a charge is present in any form. An electric field is also described as the electric force per unit charge. The formula of electric field is given as; E = F /Q.
What is electric field unit?
The SI unit of the electric field is volts per meter (V/m). This unit is equivalent to Newton’s per coulomb. These are derived units where Newton is a unit of force and Coulomb is the unit of charge.
What is electric field write its SI unit?
Definition- the electric field intensity is defined as the ratio of the force →F experienced by the charge and the amount of the charge q . ∴→E=→Fq. Force is a vector quantity. The SI unit of the electric field intensity is volt/meter or V/m.
What is electric field direction?
The direction of an electrical field at a point is the same as the direction of the electrical force acting on a positive test charge at that point.
What is the electric field formula?
The units of electric field are N/C. E = F q test = k | Q | r 2 . … This equation gives the magnitude of the electric field created by a point charge Q. The distance r in the denominator is the distance from the point charge, Q, or from the center of a spherical charge, to the point of interest.
What is an electric charge Class 12?
“Electric Charge is the property of subatomic particles that causes it to experience a force when placed in an electric and magnetic field.”
