What else can I help you with?
Explain free electron concept and electric current?
the flow of electrons in semi conductor is called electric current. the electrons revolved around the nucleas is called free electrons
The unit of current?
you can measure the unit of a current in amps (A) we measure the current using a ammeter
What are normally open and close circuits?
The electric path which starts from the positive terminal of a cell or battery ends at its negative terminal, without any break, is called closed electric circuit or complete electric circuit. The electric path,which starts from the positive terminal of a cell or battery, is broken at some point, is called open electric circuit or incomplete electric circuit.
What is the instrument called that measures current?
The instrument used to measure electrical current is called an ammeter, which is actually a shortened form of 'amp meter'. The current is measured in amperes. In scientific labs, a much more sensitive instrument called a galvanometer is used to measure very small currents.
What is the material of adding some impurities to semiconductor material?
Its called doping.
What material conducts electric current poorly?
A material that conducts electric current poorly is an insulator. Insulators have high resistance to the flow of electricity due to their tightly bound electrons, which do not move easily. Examples of insulators include rubber, plastic, and glass.
An acid base or salt which when dissolved in water conducts an electric current is called what?
It's called an electrolyte
What is the continuous flow of electric charges through a material?
Yes, an electric current is the flow of charged particles.
What is a material with little resitance to electric current called?
This is called a conductor.
What is Decomposition of a material by an outside electric current call?
The process of decomposing a material by an outside electric current is called electrolysis. It involves passing an electric current through a substance to break it down into its component parts.
What is a material called that allows an electric current to flow through it?
A conductor.
Is this sentence incorrect any material that allows an electric current to pass through is called a battery?
Incorrect. Any material that allow electric current to pass through it is a conductor.
What is the flow of electrical charges called?
It is called an electric current.
What is the movement of electrical charge on a material called?
The movement of electrical charge on a material is called electric current. It is defined as the flow of electric charge through a medium, such as a wire, in response to an electric field.
Is the continuous flow of charges through a material is called electric resistance?
No, it's called 'current'.
What material has high resistance to the flow of electric current?
The material that has high resistance to the flow of electric current is called an insulator. Examples of insulating materials include rubber, glass, and plastic.
What is a material that easily allows the flow of electric charge through it is called a semiconductor b insulator c superconductor d conductor?
conducts
