A conductor has more free electrons at the outer shell (valence) of its atoms. These free electrons move when an electric current is applied across the substance. Insulators, on the other hand, do not have as many free electrons and will take a stronger amount of energy for it to conduct the flow of electrons.
In the real world, there are very few real insulators since lightning can flow across anything if the right circumstance exist.
What else can I help you with?
Why do we need different materials?
Different materials serve different purposes based on their properties. For example, some materials are better at conducting electricity, while others are better at insulating. Using a variety of materials allows us to design and create products that are more efficient, durable, and versatile.
Which type of substance would you use as a insulating material for a hot mitt?
A heat-resistant material such as silicone or a blend of cotton and polyester would be suitable for an insulating material in a hot mitt. These materials can withstand high temperatures and provide protection against heat.
When a substance changes into a different substance a what change has occurred?
Chemical change.
How can one identify an unknown substance in chemistry?
One can identify an unknown substance in chemistry by conducting various tests such as spectroscopy, chromatography, and chemical reactions to determine its properties and compare them to known substances.
When equal amounts of energy are transferred to or from equal masses of different substance the substance will undergo different changes in temperature because of their different?
specific heat capacities. The substance with the lower specific heat capacity will experience a greater change in temperature compared to the substance with a higher specific heat capacity.
What materials has both conducting and insulating properties?
Semiconductors.
Is a bottle a good conductor?
Cork exhibits insulating properties. Not conducting.
What type of substance would you use as as insulating material for a hot mitt?
Silicon is a type of substance you can use as a insulating material for a hot mitt.
Is a bottle cork a good conductor?
Cork exhibits insulating properties. Not conducting.
Are all thermally conducting materials also electrically conducting?
no. for example ceramic insulating heat sink wafers conduct heat very well from an electronic component to a metal heatsink while insulating the component electrically from the heatsink.
Is an electrical plug an insulator?
An electrical plug contains both conducting and insulating elements.
What is a material that can exhibit both insulating and conducting properties?
Graphene is a material that can exhibit both insulating and conducting properties. In its pristine form, graphene is a highly efficient conductor due to its unique 2D structure. However, by introducing defects or doping, graphene can also exhibit insulating behavior, making it a versatile material for various electronic applications.
What is the difference between conducting and non conducting sphere?
Conducting spheres allow for the flow of electric charge, while non-conducting spheres do not. Conducting spheres can redistribute charge in response to an external electric field, while non-conducting spheres cannot. Conducting spheres are typically made of metals, while non-conducting spheres are typically made of insulating materials.
How is the process of conducting electricity affected by the presence of an insulating sphere?
When an insulating sphere is present, it can block the flow of electricity because insulating materials do not conduct electricity well. This can prevent the electricity from passing through the sphere and instead force it to find an alternate path.
Why do you use waveguide instead of coaxial?
Coaxial cable is an electrical cable consisting of a round conducting wire, surrounded by an insulating spacer, surrounded by a cylindrical conducting sheath, and usually surrounded by a final insulating layer.waveguide may refer to any linear structure that conveys electromagnetic waves between its endpoints.
How a transparent mobile works?
may be some kind of materials which has the property of transparency and also which can be used for conducting, insulating,semiconducting.
Why do we need different materials?
Different materials serve different purposes based on their properties. For example, some materials are better at conducting electricity, while others are better at insulating. Using a variety of materials allows us to design and create products that are more efficient, durable, and versatile.
