In an electrical circuit ,, resistance is the force that resists the flow of electricity thru the circuit .. this is used in light bulbs to create the heat and light that we expect from the bulb .. and heat in a toaster fron the resistance in a wire making it hoy enough to cook the surface of the bread
What else can I help you with?
The opposition to the movement of charges flowing through a material is called what?
The opposition to the movement of charges flowing through a material is called resistance. It is a property that determines how strongly a material resists the flow of electric current.
What is the movement of electric charges in a closed circuit?
Electric Current
What is the basis of statement that lines of electric force begin end only in charges?
The basis for this statement is the concept of electric field lines originating from positive charges and terminating on negative charges. This is in accordance with the fundamental property of charges where opposite charges attract each other. Therefore, electric field lines cannot start or end in empty space, as they always originate from and terminate on charges.
What does the law of electric charges say about two objects that are positive charged?
the law of electric charges states that like charges repel, or push away, and opposite charges attract.
What particles have negative electric charges equal to the positive charges of the protons?
The electrons; their negativity cancels out the protons' positivity so the atom is electrically neutral.
The property of substance that hinders the motion of electric charges and converts electric energy into other forms of energy is?
resistance.
What factors affect force between electric charges?
The factors that affect the force between electric charges include the magnitude of the charges, the distance between the charges, and the medium through which the charges interact. The force between charges decreases as the distance between them increases, following an inverse square law. Additionally, the presence of a medium can affect the force through factors such as permittivity.
What opposing force must be overcome by charges blowing in electric current?
Resistance is the opposing force that must be overcome by charges blowing in an electric current. Resistance is caused by factors like the material of the conductive medium, its temperature, and the dimensions of the conductor.
What opposing force must be overcome by charges flowing in electric circuits?
The opposing force that charges flowing in electric circuits must overcome is resistance. Resistance is caused by factors such as the material through which the charges are flowing, the temperature of the material, and the dimensions of the material. It impedes the flow of charges and results in the conversion of electrical energy into heat energy.
The opposition to the movement of charges flowing through a material is called what?
The opposition to the movement of charges flowing through a material is called resistance. It is a property that determines how strongly a material resists the flow of electric current.
Is the continuous flow of charges through a material is called electric resistance?
No, it's called 'current'.
How is electric potential generated in a conductor during the flow of charges?
Electric potential in a conductor is generated by the movement of charges, creating an electric field. As electrons flow through the conductor, they experience a resistance, which causes a potential difference to develop. This potential difference creates an electric field that drives the flow of charges.
How does electrical resistance affect the movement of charges?
It acts like friction in mechanical systems.
What factors affect an electric charge?
Factors that affect an electric charge include the number of electrons or protons present, the distance between charges, and the material through which the charges are moving. Additionally, the presence of an external electric field can influence the charge and its behavior.
What factors affect the force between charges?
The force between charges is affected by the magnitude of the charges, the distance between the charges, and the medium in which the charges are located. The force increases with the magnitude of the charges and decreases with the distance between the charges. The medium can affect the force through its electric permittivity.
What is true about current?
It is measured in amps. It is related to voltage and resistance by Ohm's Law. It is the flow of electric charges.
What is a material that blocks the flow of electric charges?
An insulator is a material that blocks the flow of electric charges. Insulators have high resistance to the flow of electrons and do not conduct electricity easily, making them ideal for preventing electric charges from flowing. Materials such as rubber, plastic, and glass are common examples of insulators.
