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.

What specifically does resistance reduce the flow of?
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
What happens when an electric current encounters resistance?
An electron traveling through the wires and loads of the external circuit encounters resistance.
Does resistance flow through a circuit?
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.
Why conductors offer resistance?
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 .
How much electromotive force is required to cause 6280000000000000000 electrons to flow per second through a circuit with 1 ohm of resistance?
1 volt is.
The measure of how difficult it is for electrons to flow through materials?
resistance
What is an electron device made of solid materials through which electrons move?
a electric plug
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.

What is an electron current?
the flow of electrons through a conductor
What is electron current?
the flow of electrons through a conductor
Why does the resistance of a conductor rise with the rise in temperature?
For metals, as the temperature rises, the atoms wiggle around more, and are more likely to be hit by an electron that is moving through the metal. The more electrons that hit the atoms, the greater the resistance. Think of the wiggling atoms as interfering with the smooth flow of electrons.
What is the materials through which electrons through a conductor?
These are metals.
How does electron pass through electricity?
An electron is electricity as we know it. Electrons flow through a conductable element and that is electricity.
How high is your body resistance?
Your body resistance is high- hard to push electrons through.
What form do proteins need to be in to go through the electron transport chain?
Stripped of their electrons by electron carriers. Electrons are the only thing going through the electron transport chain, where their motive force is moving protons across membranes.
Which of these is encountered by the electrons while flowing through a conductor?
Resistance
