Difference between electron flow and conventional current?
Conventional current flow refers to a flow of positive charges. It is a kind of ficticious current. If - as is often the case - the real current is an electron flow (negative charges), then the conventional flow is a current in the opposite direction as the electron movements, since this would have the same effect (for example on the magnetic field, or on conservation of charge).
What is a conventional current?
Conventional current shows current flow from + to - amp meters are labeled this way (conventional current flow) (hole flow) Physics shows that electrons are moving or flowing from - to + (electron flow) Tubes (deforest valves) sort of blew conventional current away semiconductors with different doping materials confuse it more so most new books relate to electron flow voltmeters ammeters are labeled the same since the 18th century
What is an easier path for electron flow that can cause shocks or an electric fire?
A Short Circuit
What is a material which allows electricity to flow through it but with but with resistance?
A "resistance" or "resistor".
Do Diodes have the ability to block electron flow in one direction and pass electrons in the opposite direction.?
yes
Tendency of material to oppose electron flow?
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.
