Materials with more resistance have a higher resistivity, which is a measure of how strongly a material impedes the flow of electric current. Factors such as the material's atomic structure, temperature, and impurities can affect its resistivity. Materials like metals tend to have low resistivity due to their abundance of free electrons, while insulating materials have higher resistivity as they inhibit the movement of electrons.
What else can I help you with?
Do all conductors have resistance?
Yes, all conductors have resistance to some degree. Resistance is a property of materials that impedes the flow of electric current. However, some materials have lower resistance (e.g., copper) while others have higher resistance (e.g., rubber).
Do some balls bounce more then others?
Yes, some balls bounce more than others due to differences in their material composition, air pressure, and elasticity. Materials like rubber typically have higher bounce compared to materials like foam. Additionally, balls with more air pressure or higher elasticity will generally bounce higher.
Why are some materials good insulators while others are not?
Materials that are good insulators have a high resistance to the flow of heat or electricity due to their molecular structure. This can include materials with tightly packed molecules or those that contain trapped air pockets, such as rubber or fiberglass. In contrast, materials that are poor insulators have more free-flowing electrons or a looser molecular structure, allowing heat or electricity to pass through more easily.
Why are some surfaces more reflective than others?
Some surfaces are more reflective than others because of their smoothness and the material they are made of. A smooth surface allows light to bounce off it more easily, creating a reflective effect. Additionally, materials with higher reflectivity properties, such as metals, will reflect more light compared to materials with lower reflectivity properties, such as wood.
Do some materials hold onto electrons more tightly than others when charging by rubbing to occur?
Yes, some materials hold onto electrons more tightly than others. This property is known as electron affinity, and materials with higher electron affinities tend to hold onto electrons more strongly when charged by rubbing. Materials like rubber or wool have higher electron affinities compared to materials like silk or glass.
Why are some materials better insulators than others?
Insulation is directly proportional to resistance. More resistance means more insulation. And if a material is denser (i.e. the particles are situated closer to each other), then the resistance is more. Hence, more density-->more resistance-->better insulation And since different materials have different density, hence they also have different insulations. hope it helps.. :)

Why can some materials have a higher resistance than others?
because of the gravity of the earth -Jade
Which element has the property of zero resistance?
The element that has the property of zero resistance is superconductors. Superconductors are materials that can conduct electricity without any resistance when they are cooled to very low temperatures.
Do some balls bounce more then others?
Yes, some balls bounce more than others due to differences in their material composition, air pressure, and elasticity. Materials like rubber typically have higher bounce compared to materials like foam. Additionally, balls with more air pressure or higher elasticity will generally bounce higher.

What are the best sites to get homeschooling materials?
Many different websites offer homeschooling materials, books and more. Some of these include HomeSchoolingBooks.com, Time4learning.com, HomeSchoolingSupply.com and others.
Does the material a balloon is made of affect the loss of air?
Yes, as some materials are more porous than others.
Why are some fabrics more biodegradable than others?
Because it depends on the different kinds of materials such as cotton or polyester.
What were some of the resistance movements within occupied Europe and Germany?
THE FRENCH RESISTANCE The french communist resistance SOE And various others
Why do some children fall ill more frequently then others living in the same locality?
The inherent personal resistance is poor compared to others in the same family or same locality.
Why some materials offer different resistance?
SOunds like a homework question. But ok I'll answer. Ceramics is one major material used for resistance. BUT if you want to impress your teacher, you can say that ALL materials (even gold) offers some level or resistance, just very little)
