The direction of the electric field vector is defined as?
Direction of the electric field vector is the direction of the force experienced by a charged particle in an external electric field.
Electric field is a vector or scalar?
Both. The electric field is a Quaternion field, a scalar e and a vector E, E = [e,E]Maxwell's Equation. 0=XE= [d/dr, Del][e,E] = [de/dr -Del.E, dE/dr + Del e] = [db/dt - Del.E, dB/dt + Del e]
What is the definition of the term dielectric?
'Dielectric' is often used in a general sense to refer to a material (such as ceramic, mica, plastic or paper) which is a poor conductor of electricity. This term is used in the classical description of a capacitor -- two electric conductors separated by a dielectric. By applying electric charge to one conductor an electric field is created. The dielectric allows the electric field to pass through it and affect the other conductors; however the dielectric prevents electrons from flowing between the conductors, so the electric field remains (and the charge remains stored on the conductor). [Side note for beginners: An electric field creates a force (measured in Volts) upon an electron or charged particle which tends to make it move. The conductor allows electrons to move easily within it. The dielectric resists the movement of electrons in it.] More generally, we speak of a 'Dielectric Field' as a mathematic description of how electric charge influences the properties of the space around it. The Dielectric field interacts with space and with any material in the space to create an 'Electric Field'. In simple terms, the electric field at any point is the product of the dielectric field at that point and the 'Dielectric Constant' of the material at that point. In more general terms, the 'electric field vector' at a point is the tensor product of the 'dielectric field vector' and the 'dielectric tensor' of the material at that point. The dielectric field is not a measurable entity, but rather a mathematical tool that allows us accurately to model the electric field, which is measurable. The article on Dielectrics at http://en.wikipedia.org/wiki/Dielectric provides more description, especially on the dielectric field model.
How is the strength of an electric field indicated with electric field lines?
Given a positive charge the electric field lines are drawn starting from the charge and pointing radially outward, ending in principle at infinity, according to the electric field strength being proportional to the inverse square of distance. From the definition of electric field we know that the modulous of the electric field is greater for smaller distances from the field generating charge. Since the electric field lines point radially outward we consider the density of lines an indication of the strength of the electirc field. If we immagine to trace a circle around the electric field generating charge, of radius slightly greater than the radius of the object which holds the charge and therefore generates the electric field, such circle will be crossed by a number 'n' of lines. The density of lines crossing the cirle will then be the circumference of the circle divided by the number 'n' of lines. For a larger circle we will have a greater circumference, but same number of lines 'n', and therefore a smaller density of lines crossing it, which idicates a lower intesity of electric field for a greater distance from the charge.
Where do electric field lines point?
The electric field lines are directed away from a positive charge and towards a negative charge so that at any point , the tangent to a field line gives the direction of electric field at that point.
What is the direction of the electric field around a charged particle?
The electric field around a charged particle points away from positive charges and towards negative charges.
What is the area around an electric charge which is strongest closest to the charged particle?
It's the electric field.
What is area around an electric charge which is strongest closest to the charged particle?
electric field
In which case does an electric field do positive work on a charged particle?
An electric field does positive work on a charged particle when the direction of the electric field is the same as the direction of the particle's movement.
What is the relationship between the direction of an electric field and the direction of the force exerted on a charged particle?
The direction of the force exerted on a charged particle is determined by the direction of the electric field. The force acts in the same direction as the electric field if the particle is positively charged, and in the opposite direction if the particle is negatively charged.
When the distance from a charged particle decreases the strength of the electric field does what?
As the distance from a charged particle increases the strength of its electric field DECREASES.
The strength of the electric field of a charged particle becomes greater as the distance from the particle increases.?
No, the strength of the electric field of a charged particle becomes weaker as the distance from the particle increases. The electric field strength follows an inverse square law relationship with distance, meaning it decreases as the distance from the charged particle increases.
The strength of the electric field of a charged particle becomes greater as the distance from the particle decreases?
Yes, the strength of the electric field of a charged particle does increase as you move closer to the charged particle. This is because electric fields follow an inverse square law, meaning that the field strength is inversely proportional to the square of the distance from the charged particle. As you move closer, the distance decreases, leading to an increase in the electric field strength.
What is the behavior of a positively charged particle when it is released in an electric field?
When a positively charged particle is released in an electric field, it will experience a force in the direction opposite to the field lines. This force will cause the particle to accelerate in the opposite direction of the field.
What is the formula for the work done by an electric field on a charged particle?
The formula for the work done by an electric field on a charged particle is given by W qEd, where W represents the work done, q is the charge of the particle, E is the electric field strength, and d is the distance the particle moves in the field.
The space around a particle through which an electric charge can exert force is?
The space around a particle through which an electric charge can exert force is referred to as the electric field. This field exists at all points in space and its strength diminishes with distance from the charged particle according to an inverse square law. Other charged particles placed in this electric field will experience a force due to the interactions between their charges.
Is the space around an electrically charged object is an electric field?
Yes, the space around an electrically charged object is filled with an electric field. The electric field represents the influence a charged object exerts on other charged objects in its vicinity. It can be thought of as a region where a force would be experienced by a charged particle placed within it.
