Why is the direction of dipole moment is from negative to positive charge?
The direction of the dipole moment is from the negative charge to the positive charge because it represents the vector pointing from negative charge towards positive charge, illustrating the net charge distribution within the molecule or system. This convention is commonly used to describe the direction of the dipole moment vector.
What determines the direction of the magnetic force on a moving charge?
The right hand grip rule. You point the thumb on your right hand in the direction of the electric current and curl your fingers. The direction of your fingers gives the direction of the lines of flux. It is undetermined what actually causes the induced charge to always be in this direction but it is probably a function of the electrons spin.
A negatively charged object is placed within a positive electric field. what happens to the object?
Electric Field between positive and negative charges. If the Electric Field in which both the positive and negative charges are present is stronger than the Electric Field between the two charges we are talking about, the the negative charge will move away from the positive charge in that positive direction of the field. If not, then the negative charge will get attracted to the positive charge and stay at the position of the positive charge. It will be pulled toward the source of the electric field. (Novanet)
What is the relationship between the direction of current and direction of electron flow in a current-carrying wire?
The direction of current flow is defined as the direction positive charge carriers would flow, which is opposite to the actual movement of electrons (negative charge carriers) in a wire. Electrons flow from the negative terminal of a power source to the positive terminal, while conventional current flows from the positive terminal to the negative terminal.
In a dc circuit polarity refers to the direction of which flow?
In the US, it is common practice in a DC circuit to refer to the polarity for which "positive (+) charge" is flowing. Positive charge (current) will flow out of a voltage supply's positive (+) terminal which means positive charge will flow into the (+) terminal of a circuit load (resistor, etc). This is an arbitrary convention and may be reversed in older or foreign textbooks. In such cases all positive (+) references in the previous description would be replaced by negative, (-) notations.
How can one determine the direction of the electric field at a specific point?
To determine the direction of the electric field at a specific point, you can place a positive test charge at that point and observe the direction in which it experiences a force. The direction of the force on the positive test charge indicates the direction of the electric field at that point.
Do electric fields point outward or inward?
Electric fields point outward from positive charges and inward toward negative charges. This direction represents the direction of the force that a positive test charge placed in the field would experience.
In which direction does the electric field point at position directly east of a positive charge?
Yes. The electric field in physics is represented by a vector, it has three components governing the field strength in the up-down, left-right and forward-backwards directions.
In which direction does the electric field point at a position directly north of a positive charge?
The electric field points directly away from a positive charge. Therefore, at a position directly north of a positive charge, the electric field would also point directly away from the positive charge.
What do electric field lines point to?
Electric field lines point towards the direction that a positive test charge placed in the field would move. They represent the direction and magnitude of the force that a positive charge would experience in that field.
In which direction does the electric field point at a position direcly south of a positive charge?
The electric field points away from a positive charge in all directions, meaning it would also point away to the south of the charge.
Why are electric field drawn with arrows?
Electric field lines are drawn with arrows to show the direction of the force that a positive test charge would experience if placed in the field. The direction of the electric field at any point is the direction that a positive test charge would move when placed in the field at that point.
What is true on electric field around a positive charge in what direction will it point at?
The electric field around a positive charge points radially outward in all directions away from the charge. The field lines point away from the positive charge and decrease in strength with distance according to the inverse square law.
Is it true that the direction of an electric field at any point by convention is the direction of the electrical force on a small negative test charge placed at that point?
Yes, that is correct. The direction of the electric field at any point represents the direction in which a positive test charge placed at that point would experience a force. If a negative test charge is used, the force it experiences would be in the opposite direction of the electric field.
Does an electric field have strength but no direction?
It has plenty of direction. The direction of the electric field at any point in it is the direction of the force that would be felt by an infinitesimally small positive charge placed at that point.
How do their directions compare with the direction of the force that acts on a positive test charge in the same region?
The electric field and force due to it in a region both point in the same direction for a positive test charge. This means that the direction of the force acting on a positive test charge will be the same as the direction of the electric field in that region.
How does a negative point charge behave in an electric field produced by a positive point charge?
A negative point charge will be attracted towards a positive point charge in an electric field.
