Note that "electricity" doesn't flow, only current does, which is one aspect of electricity, does. Current is the flow of electrons. The main materials that do not allow the easy flow of electrons are rubber, nylon wood, glass, ceramic, plastic and free air.
Insulators
Because of freely moving of electrons in the material
The Materials are of three kinds:- Conductors- Semiconductors and- InsulatorsThe Insulators have the property to stop the flow of electricity, because they have less number of free electronics, which can conduct Electricity.
electrons can flow through circuits.
Resistance slows the flow of electrons in a conductor.When you say that a substance has resistance, it actually means that the substance slows down the flow of electrons, thereby reducing the current. So, higher the resistivity of a substance, lesser the velocity of the electrons in the circuit assuming all the other values constant.
Any device as soon as electrons flow there is restriction caused by materials opposing this electrons flow.
electrical resistence is occur in conductor due to over flow of current,in conductorAnswerResistance is not due to the 'flow of current'. It exists whether current is flowing or not! Resistance is determined by the type of material and its physical dimensions. Resistance depends upon the resistivity (which is also affected by temperature) of the material, and the length and cross-sectional area of that material.

Loads do not 'slow down' electron flow. They effect the magnitude of a current, not its speed!

Yes, when the flow of a river slows the sediment is deposited.

The flow of water slows enough for the silt to be deposited.
Conducting materials readily give and receive electrons from one atom to another. Electric current is actually the flow of electrons, so if it's difficult for the electrons to move, there will little or no current flow.
