Does electric field depend on charge?
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.
Does this electric field depend on the charge of the test charge q?
The electric field is thus seen to depend only on the charge Q and the distance r; it is completely independent of the test charge q.
What is the position of a charge in an electric field gives it electric?
Electric field is a vector quantity whose direction is defined as the direction that a positive test charge would be pushed when placed in the field. Thus, the electric field direction about a positive source charge is always directed away from the positive source.
Does the work done by the electric field on the charge depend on the path that the charge takes to get from one point to another?
Electric potential energy of two point charges The work done by the electric field of one point charge on another does not depend on the path taken. Therefore, the electric potential energy only depends on the distance between the charges.
Does electric field depend on area?
The strength of an electric field as created by source charge Q is inversely related to square of the distance from the source. This is known as an inverse square law. Electric field strength is location dependent, and its magnitude decreases as the distance from a location to the source increases.
Does electric field depend on area of cross section?
The electric current remains constant in the wire so that no charge accumulates in the wire. The drift speed and current density depends on the area of cross section and hence they do not remain constant. From the relation j=σE, it can be deduced that the electric field does not remain constant.
What is the direction of the electric field at position of the DOT due to the negative point charge as shown?
Electric Field due to positive charge is directed outwards, while due to negative charge is inwards. The Net electric field at a point due to multiple charges is calculated by vector addition of fields due to every individual positive and negative charges.
Does electric field depend on Path?
Electricity is a conservative force, so the work done by it doesn’t depend on the path taken.
Does the work done by electric field depend on Path?
This work is the electric energy or the electric potential energy of the charge. This implies, the work done on any particle moving under its influence does not depend on the path taken by the particle but depends on initial and final positions of the particle.
How does electric field vary with area?
Both electric field and current density are a properties of points in space. Since current density is defined as current per cross sectional area, in order to maintain same current through out the conductor the current density changes with cross sectional area.
Does electric field depends on area of cross section?
Is electric energy dependent on the position of a charge?
Q: Is electric energy is dependent on the position of a charge in on electric field but not on the magnitude of the charge? A: If the electric field is a potential field (no swirl) the work needed to bring a charge of magnitude Q from infinity to the point where the potential is U – thus the potential energy stored – equals Q*U.
Does charge depend on the magnitude of the charge on potential?
So yes it directly depends on the magnitude of the charge. The position in the field is irrelevant as such, but the potential is most often a function of the position so it will depend on the potential indirectly, too.
What is the change in potential energy when a charge moves?
The change in potential energy or the work done depends on the size of the charge being moved. Figure 20–2 Electric field and electric potential As a charge q 0 moves in the direction of the electric field, E, the electric potential, V, decreases.
What is the electric field acting on an electric charge?
So the same principal also applies to the electric field acting on an electric charge. We define the electric potential as the potential energy of a positive test charge divided by the charge q0 of the test charge.
