What else can I help you with?
When electric bulb glows filament only glows and supporting metals do not why?
The supporting metals are insulated from the current path and current cannot flow.
Which metals that are not conductor that did not permit the flow of electric?
Metals that are poor conductors of electricity include tungsten, bismuth, and manganese. These metals have high resistivity due to their electron configuration, which hinders the flow of electric current through them.
What is the electrical current in a circuit?
Conventionally electric current was assumed to be a flow of positive charges. But in reality especially in metals electric current is due to the flow of negatively charged electrons. So direction of conventional current is opposite to the direction of flow of electrons. But in case of liquids as well as solids electric current is due the flow of both positive and negative ions.
Why are charges not able to flow through plastics?
Plastics are insulators, which means they have a high resistance to the flow of electric charges. This is due to the absence of free electrons that are necessary to carry electric current. As a result, charges are not able to flow easily through plastics like they can through conductors such as metals.
What is a cuductor and a insolator?
A conductor is a material that allows the flow of electric current, such as metals. An insulator is a material that does not allow the flow of electric current, such as rubber or glass. Conductors have low resistance to electrical flow, while insulators have high resistance.
How electric current flow in metal?
Electric current flows in metals due to the movement of free electrons. When a voltage is applied across a metal conductor, the electric field created causes the free electrons to move in the direction of the field, creating a flow of charge which we refer to as electric current.
Do metals let electricity flow through them?
Yes, metals are good conductors of electricity because their atomic structure allows for the movement of electrons, which enables the flow of electric current.
The flow of electric charges is called?
The flow of electric charges is current.
What is the flow electric charges called?
It is called an electric current.
Why are metals good conductors of electric current?
Metals are good conductors of electric current because they have loosely held electrons in their outer shells, which are free to move and carry charge. This electron mobility allows for the easy flow of electric current through the metal. Additionally, the lattice structure of metals provides a pathway for the movement of electrons.
Is a cotton string good conductor?
No, cotton is an insulator and not a good conductor of electricity. Conductors are typically materials like metals that allow the flow of electric current, while insulators like cotton inhibit the flow of electric current.
What is the result when an electric current is interrupted?
When an electric current is interrupted, the flow of electrons is halted and no electricity is able to pass through the circuit. This can result in devices or appliances not functioning properly until the current is restored.
