Can a stationary charge produce electric field?
A stationary charge will produce only an electric field in the surrounding space. If the charge is moving, a magnetic field is also produced. An electric field can be produced also by a changing magnetic field.
What is the dimension of electric field?
Or, E = [M1 L1 T-2] × [I1 T1]-1 = [M1 L1 T-3 I-1]. Therefore, the Electric Field is dimensionally represented as [M1 L1 I-1 T-3].
Does electric field contain energy?
The energy of an electric field results from the excitation of the space permeated by the electric field. It can be thought of as the potential energy that would be imparted on a point charge placed in the field.
When a charge particle is stationary then it produces?
Answer: A stationary charged particle produces an electric field, for a negatively charged particle the field lines are directed radially inwards, for a positively charged particle the field lines are directed radially outward, as is shown in the diagram.
Does electric field have direction?
Because an electric field has both magnitude and direction, the direction of the force on a positive charge is chosen arbitrarily as the direction of the electric field. Because positive charges repel each other, the electric field around an isolated positive charge is oriented radially outward.
What determines the direction of an electric field?
The direction of the electric field is always directed in the direction that a positive test charge would be pushed or pulled if placed in the space surrounding the source charge. A more useful means of visually representing the vector nature of an electric field is through the use of electric field lines of force.
What is electric field produced by a charge find dimensions of electric field intensity?
The space around an electric charge in which its influence can be felt is known as the electric field. The electric field intensity at a point is the force experienced by a unit positive charge placed at that point. Formula: Electric Field = F/q. Unit of E is NC-1 or Vm-1.
What does electric field depend on?
The strength of the electric field depends on the source charge, not on the test charge. Because an electric field has both magnitude and direction, the direction of the force on a positive charge is chosen arbitrarily as the direction of the electric field.
How electric field is produced?
The electric field is produced by stationary charges, and the magnetic field by moving charges (currents); these two are often described as the sources of the field. The way in which charges and currents interact with the electromagnetic field is described by Maxwell’s equations and the Lorentz force law.
