Materials electricity can not pass through?
as u know the voltage from the supply V=IR and for the electricity to pass through I=V/R so when R=∞ so I=0 , so the materials having very high resistance (R) is the materials that the electricity cant pass at the normal voltage which are called insulators usually non-metals like ( benzene , wood , paper , plastics , cotton , glass , ceramic , porcelain, ..... ) but for very high voltage happens surge at which this materials be conductors normal voltage = 120 , 220 high voltage =120,000 220,000
What can survive 1250 degrees?
Materials that can withstand temperatures of 1250 degrees Celsius include certain ceramics, such as alumina and zirconia, as well as some superalloys and refractory metals like tungsten and molybdenum. Additionally, certain types of thermal insulation, such as aerogel and specific high-temperature fiberglass, can also endure such extreme heat. These materials are often used in aerospace, industrial furnaces, and other high-temperature applications.
What is thermosetting materials?
Thermosetting materials fuse under heat. The change is usually permanent.
What are two dimensional instructional materials?
Two-Dimensional Materials Chart Graph Map Photograph Cartoon Poster Diagram
List two materials required for composite making?
Carbon and glass fiber are two materials that are required for composit making.
What is the difference between lvalue and rvalue?
A variable is a named storage that can hold any value and has 2 values associated with it namely rvalue and lvalue. 'rvalue' is its data value that is its content and "lvalue" is its location value, that is memory address.
What is lvalue?
A variable has two associated value with it rvalue and lvalue. 'lvalue' is its location value, that is memory address.
What materials are used to build a magnet?
Materials with high coercivity and high retentivity.
When was High Energy Materials Research Laboratory created?
High Energy Materials Research Laboratory was created in 1960.
What is Lvalue in c?
An lvalue is an object that can be assigned a value, i.e. it can be on the left side of an equals sign, hence the term lvalue.If the compiler is complaining, you are probably trying to assign a new value to an rvalue, such as an array name or constant.
What materials have a high density?
Materials such as lead, gold, platinum, tungsten, and osmium have high densities due to their atomic structures and high atomic masses. These materials are commonly used in applications where their high density is advantageous, such as in radiation shielding or in precision instruments.
What kind of materials does Switzerland make its high quality goods?
Switzerland makes high quality goods from imported materials.
What materials can withstand high temperature?
There are two non-metal materials that come to mind. Ceramics and diamond can withstand high temperatures.
What nonmetal materials can withstand high temperatures?
Nonmetal materials that can withstand high temperatures include ceramics (such as alumina and zirconia), refractory metals (like tungsten and molybdenum), and certain composite materials (such as carbon-carbon composites). These materials have high melting points and good thermal stability, making them suitable for high-temperature applications.
Why high energy materials has so high energy?
High energy materials have high energy due to the presence of chemical bonds that release a significant amount of energy when they are broken. These materials are designed to contain a large amount of stored energy that can be released rapidly, making them ideal for explosive applications. Additionally, the specific composition and structure of high energy materials contribute to their high energy content.
Does metal have high thermal conductivity compared to other materials?
Yes, metal generally has high thermal conductivity compared to other materials.
What is materials are incombustible?
Materials that are considered incombustible include mineral wool, gypsum board, concrete, and steel. These materials have high fire resistance and do not ignite easily when exposed to high temperatures or flames.
