An electric field is a region surrounding electrically charged particles where a force is exerted on other charged particles within that region. It represents the influence that a charged particle would have on another charged particle placed in that field. The direction of the electric field is defined as the direction that a positive test charge would feel a force if placed in the field.
The electric field is defined as the force per unit positive charge that would be experienced by a stationary point charge at a given location in the field.

What do you mean by electric flux?
Electric flux measures the flow of electric field through a surface. It is defined as the dot product of the electric field and the normal to the surface, integrated over the surface area. It represents the number of electric field lines passing through a given area.
What does a positive mean for electric field strength?
A positive electric field strength indicates that the field is directed away from a positive charge or towards a negative charge. It signifies the direction in which a positive test charge would move if placed in the electric field.
Why does the electric field inside a dielectric decrease when it is placed in an external electric field?
The net electric field inside a dielectric decreases due to polarization. The external electric field polarizes the dielectric and an electric field is produced due to this polarization. This internal electric field will be opposite to the external electric field and therefore the net electric field inside the dielectric will be less.
Which of the following are created by an arrangement of electric charge or a current?
for apex its: a quantum field, a gravitational field
What is relation between electric field intensity and electric potential?
Electric field intensity is related to electric potential by the equation E = -∇V, where E is the electric field intensity and V is the electric potential. This means that the electric field points in the direction of steepest decrease of the electric potential. In other words, the electric field intensity is the negative gradient of the electric potential.

What is electrical fields?
If you mean an electric field it is the field that surrounds an electric charge. If you have two parallel plates with positive and negative charges, the amount of electric field in the space between the plates is the voltage difference divided by the distance. Electric field E is measured in volts per metre.
What does a positive mean for electric field strength?
A positive electric field strength indicates that the field is directed away from a positive charge or towards a negative charge. It signifies the direction in which a positive test charge would move if placed in the electric field.

What is the area around an electric charge which is strongest closest to the charged particle?
It's the electric field.
Can an electric field exist without a magnetic field?
Yes, an electric field can exist without a magnetic field. Electric fields are produced by electric charges, while magnetic fields are produced by moving electric charges. So, in situations where there are stationary charges or no current flow, only an electric field is present.
What is relation between electric field intensity and electric potential?
Electric field intensity is related to electric potential by the equation E = -∇V, where E is the electric field intensity and V is the electric potential. This means that the electric field points in the direction of steepest decrease of the electric potential. In other words, the electric field intensity is the negative gradient of the electric potential.
Why electric field lines cannot have sudden brakes in between them?
Electric field lines represent the direction of the electric field at any point in space. If there were sudden breaks in the field lines, it would imply sudden changes in the electric field strength, which is not physically possible. The electric field must vary continuously and smoothly in space.
Moving electric charges will interact with?
Moving electric charges will interact with magnetic fields, experiencing a force perpendicular to the direction of their motion. This phenomenon is known as the Lorentz force.
Why electric line of force can not have sudden break?
Electric field lines represent the continuous flow of electric field from one point to another. If there were a sudden break in the electric field line, it would imply a sudden discontinuity in the electric field strength, which is not physically possible. This is because electric field lines are a visual representation of the direction and strength of the electric field, which must be continuous to maintain the conservation of electric field flux.
How closely packed the electric field lines are indicates the strength of the electric field?
true
