What makes up electric force?
Electrical forces result from mutual interactions between two charges. In situations involving three or more charges, the electric force on a single charge is merely the result of the combined effects of each individual charge interaction of that charge with all other charges.
What is electric force equal to?
The electric force between two electrons is equal to the electric force between two protons when placed at equal distances. This describes that the electric force is not based on the mass of the object, but depends on the quantity known as the electric charge.
What are the types of electric force?
Types of electric force Electrical force consists of two different types of charges. They are positive electric charge and negative electric charge. The interaction of both of these charges is easily predictable. Unlike electric charges, they attract each other, while the like charges repel one another.
What are electric forces for kids?
An electric force is exerted between any two charged objects. Objects with the same charge, both positive and both negative, will repel each other, and objects with opposite charges, one positive and one negative, will attract each other.
What two things will make the electric force stronger between two objects?
When you have two charged particles, an electric force is created. If you have larger charges, the forces will be larger. If you use those two ideas, and add the fact that charges can attract and repel each other you will understand Coulomb’s Law. It’s a formula that measures the electrical forces between two objects.
What moves electric current?
In electric circuits the charge carriers are often electrons moving through a wire. In semiconductors they can be electrons or holes. In an electrolyte the charge carriers are ions, while in plasma, an ionized gas, they are ions and electrons….

What are two types of electric current?
Current electricity is a constant flow of electrons. There are two kinds of current electricity: direct current (DC) and alternating current (AC). With direct current, electrons move in one direction.
What affects electric force?
The first factor is the amount of charge on each object. The greater the charge, the greater the electric force. The second factor is the distance between the charges. The closer together the charges are, the greater the electric force is.
Which is an example of an electrical force?
The examples of electric force are as mentioned below: The charge in a bulb. Electric circuits. Static friction between cloth when rubbed by a dryer. The shock that is felt after touching a doorknob.
When is an electric force attractive or repulsive?
An electric force is an attractive or repulsive force between two charged objects. Electric forces are attractive when two objects have opposite charges and repulsive when two objects have like charges.
How are electrical forces different from magnetic forces?
Electric forces are attractive when two objects have opposite charges and repulsive when two objects have like charges. Electric forces are different from magnetic forces, although the two are strongly related. Static electric forces are relatively easy to observe in action.
Where does the direction of the electric force come from?
The direction of the force can be found by inspection. The electric force always acts along the line between the two point charges. For this problem, the charges have opposite signs, so we know they attract. We add force vectors to the diagram, The magnitude of the force comes from Coulomb’s Law.
