Electrons are said to carry negative charge while protons are said to carry positive charge although these labels are.
Electric field of positive and negative charge.
Two negative charges repel.
An electric field is a region of space around an electrically charged particle or object in which an electric charge would feel force.
Consider the diagram above in which a positive source charge is creating an electric field and a positive test charge being moved against and with the field.
Consider a unit charge q placed in a vacuum.
The electric field is represented by the imaginary lines of force.
The pattern of lines sometimes referred to as electric field lines point in the direction that a positive test charge would.
Also two positive charges repel.
Field lines must begin on positive charges and terminate on negative charges or at infinity in the hypothetical case of isolated charges.
The number of field lines leaving a positive charge or entering a negative charge is proportional to the magnitude of the charge.
The direction of an electrical field at a point is the same as the direction of the electrical force acting on a positive test charge at that point.
An electron is considered the smallest quantity of negative charge and a proton the smallest quantity of positive charge.
A useful means of visually representing the vector nature of an electric field is through the use of electric field lines of force.
For the positive charge the line of force come out of the charge and for negative charge the line of force will move towards the charge.
The electric field for positive and negative charges are shown below.
Like charges repel each other and unlike charges attract each other.
For example if you place a positive test charge in an electric field and the charge moves to the right you know the direction of the electric field in that region points to the right.
In brief electrons are negative charges and protons are positive charges.
When this principle is logically extended to the movement of charge within an electric field the relationship between work energy and the direction that a charge moves becomes more obvious.
The properties of electric field lines for any charge distribution are that.
An electric charge is a property of matter that causes two objects to attract or repel depending on their charges positive or negative.
A pattern of several lines are drawn that extend between infinity and the source charge or from a source charge to a second nearby charge.
Electric polarization slight relative shift of positive and negative electric charge in opposite directions within an insulator or dielectric induced by an external electric field polarization occurs when an electric field distorts the negative cloud of electrons around positive atomic nuclei in a direction opposite the field.
Positive and negative commonly carried by protons and electrons respectively.
An object with an absence of net charge is referred to as neutral.
