resistance
It is called resistance Good conductors have a bad resistance While bad conductors or insulators have good resistance against the flow of electricity
Electron flow is known as current. SI unit is Ampere
The "flow of current" is considered to be in the opposite direction.
oppose changes in current flow.
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.
ohms law (resistance)
The tendency for a material to oppose the flow of electrons and convert electrical energy into thermal energy and light is known as resistance. This property is determined by the material's resistivity and is quantified in ohms (Ω). The higher the resistance of a material, the more it will convert electrical energy into heat and light.
The term that describes the ability of a material to oppose the flow of electric current is resistance. It is measured in ohms and is influenced by the material's properties like conductivity and temperature.
No, that statement is not accurate. Ohm's law states that the current flowing through a conductor is directly proportional to the voltage applied across it, given a constant temperature. It describes the relationship between current, voltage, and resistance in a circuit.
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.
Materials that permit electron flow are called conductors. Metals such as copper, aluminum, and gold are good conductors of electricity due to their free-moving electrons. This allows for the efficient flow of electrons through the material.
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.
Materials that oppose the flow of current are called insulators. Common examples include rubber, plastic, glass, and ceramic. Insulators have high resistance to the flow of electricity due to their atomic structures that do not easily allow the movement of electrons.
Definition Of Resistance In Electrical:Property of a material to oppose the flow of electric current through it is called Resistance.
Those are the materials we loosely call "conductors".
Active flow wet material refers to substances that can flow freely or easily when wet. This can include things like slurry, sewage, or other types of liquid waste that maintain fluidity even when mixed with water. These materials can be challenging to manage and transport due to their tendency to flow.
