resistance
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.
glass
The measure of how difficult it is for electrons to flow through a circuit is called resistance.Another AnswerResistance is not a measure of 'how difficult' it is for electrons to flow through a circuit. It is more accurate to describe it as a measure of whether a material can supportcurrent flow.For example, it's incorrect to say that an insulator 'blocks' current flow. It's more accurate to say that it has an insufficient amount of charge carriers to support an electric current.
Insulators are materials through which electrons have the most difficulty flowing. This is because insulators have very few free electrons that are able to move through the material. Materials like rubber, plastic, and wood are good examples of insulators.
These are metals.
Resistance.
insulators
Electricity moves through materials when there is a flow of charged particles, typically electrons, along a pathway provided by the material's structure. Conductive materials such as metals have free electrons that can move easily through the material, allowing electricity to flow. Insulating materials, on the other hand, impede the flow of electrons, preventing electricity from moving through them.
Current measures the flow of electrons through a circuit and voltage basically measure the amount of available electrons.
Amperage.
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.
