What is the characteristic of a material that hinders electron flow?
It is called resistance Good conductors have a bad resistance While bad conductors or insulators have good resistance against the flow of electricity
What is the unit for measuring the rate of electron flow in a circuit?
Electron flow is known as current. SI unit is Ampere
What flow is equal to and opposite of electron flow?
The "flow of current" is considered to be in the opposite direction.
What is the role of inductance in lcr circuit?
oppose changes in current flow.
What is resistance What is an electron Can electrons flow through all materials What materials are good for an electron to go through Is resistance inside of an electron?
Electrical resistance is just that: obstruction to the flow of electrons, which are (generally speaking) electric current. Electrons are what orbit the nucleus of an atom. You can force them out of their various orbital shells by using the proper voltage. Many non-conductive materials are not suitable for electron flow because they have a high resistance, e.g. glass. But if you send enough voltage through materials with high resistance the electrons will arc through the air across the top of the material. Note: You can, with a high enough voltage applied in a particular manner, cause the material itself to "fail" and conduct electricity. The high voltage will destroy the material when it ionizes the atoms within it. We can generate voltages high enough to punch through anything. Almost anything metallic is a good material for an electron to go through. In general, metals are good conductors of electricity. They have a low resistance.
Tendency of a material to oppose electron flow?
ohms law (resistance)
What is the tendency for a material to oppose the electron flow and change electrical energy in to thermal energy and light?
Resistive tendency
''Ohm's law is the tendency for material to oppose the flow of electrons''is this true?
No, resistance is the tendency to oppose the flow of electrons. Ohm's Law simply relates resistance, voltage, and current.
What material permits electron to flow?
Conductors.
What is the specific resistance that the body provides?
It is the net resistance offered by the body of unit length and unit cross section area at a given temperature to the flow of electrons. It is the constant for a material dependent on temperature. It gives the ability of the material to oppose the flow of electron when electric field is applied.
What is the ability of a material to oppose the movement of electrons through it?
A material that has a high resistance to the flow of electrons is an insulator.
Why it is that electron does not flow there is no current flowing?
Electrons are in random motion in a material, such that there is no resultant electron movement. Hence a material has no current flow by its own. Only the directed flow of this charge in a direction, will results in current. when we provide sufficient energy (for example by mean of applied potential difference ) the net motion of the electron gives rise to the current flow.
In order to be considered a semi-conductor the material must?
easily accept electron flow.
What is the meaning of electrical resistance?
Definition Of Resistance In Electrical:Property of a material to oppose the flow of electric current through it is called Resistance.
What is a material that allows electron to flow easily or with little resistance?
Those are the materials we loosely call "conductors".
What is a material that does not let electrons travel through it?
Generally speaking, a material that does not let electrons travel through it, a material that has a very high resistance to electron flow (electric current), is called an insulator.
Why plastic is a insulator why not a conductor?
firstly do you mean and insulator of heat or current? in solids heat is transferred by the free electrons in the material so if the material has no free electron (e.g plastic) then heat cant dissipated throw it. current (electricity) is a flow of electrons so if there are no free electron no current can flow. i hope that answers your question.
