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.
Resistance is the opposition of the atoms in any materiel to the movement of the electrons of a certain current ... so the resistance is a long wire, and thus more atoms to pass through that's how it reduces the electron flow
An electron traveling through the wires and loads of the external circuit encounters resistance.
No. Resistance does not flow. Resistance is the characteristic of a material that resists the movement of electrons and thus the flow of electrical current.
Yes , all conductors have some amount of resistance although it varies depending on the material that is conducting the electricity . Copper has a very low resistance, and aluminum has a slightly higher ( but still quite low ) resistance . This is why they are used as electrical conductors. Conductor resistance results in voltage drop over the conductor and power loss, manifested as heating of the conductor . Therefore , you want as low a conductor loss as is reasonably practical . The reason of resistance is that, no electron has a linear motion when an electric field is applied to it . e- move in random due to apparent collision with other e -' s. This motion is termed to as Brownian motion . The random movement however interrupts with the electric field and creates resistance sue to a negetive field generated .

resistance
The nature of materials affects resistance because different materials have varying numbers of free electrons, which are responsible for conducting electricity. Materials with more free electrons, like metals, have lower resistance since electrons can flow more easily through them. Conversely, insulating materials have high resistance because they have very few free electrons available for conducting electricity.
a electric plug
Electrons find it most difficult to flow through insulating materials like rubber, glass, and plastic. These materials have very high resistance to the flow of electric current, which makes it harder for electrons to move through them.
That tendency is known as electrical resistance. It is a measure of how difficult it is for an electric current to pass through a substance. Materials with high resistance impede the flow of electrons, while materials with low resistance allow electrons to flow more easily.
That ability is called electrical resistance. Materials with high resistance impede the flow of electrons, while those with low resistance allow electrons to pass through more easily. The unit of measurement for electrical resistance is the ohm (Ω).
Electrons move easily through materials with low resistance, such as metals like copper and aluminum. These materials have a high conductivity, which allows electrons to flow through them more easily.
glass
Electrons do not readily flow through insulating materials, which have a high resistance to the flow of electric current due to their tightly bound electrons. Examples of insulating materials include rubber, plastic, and glass.
Electrons have difficulty moving around an electric current in certain materials because of resistance. Resistance is caused by collisions with other atoms and impurities in the material that hinder the flow of electrons. This resistance generates heat energy and limits the ability of electrons to move freely through the material.
Materials that have high resistance do not allow electrons to move easily through them. This can be due to factors such as the material's atomic structure, temperature, or impurities present in the material.
The presence of free electrons is the primary characteristic of an element that makes it a good conductor of electricity. Materials with a high number of free electrons can easily carry electric current because the electrons are able to move through the material with little resistance.
