How a transistor constructed?
They contructed using semiconducters and metals. BJT(Bipolar junction Transisters) type transisters made by semi conducters. Generally for FET (Field Effect Transisters) type sometimes they add some metals to get the expected output.
How many type impeller?
Three types of impeller. A- Semi open B- Open C- Close Rajeev Singh
What is the cubical coefficient of thermal expansion for metals?
Since most metals are isotropic, the cubical coefficient of expansion is three times the linear coefficient of expansion. The linear coefficient of expansion is obtained from measurement and tables for the specific material which are readily available.
What are the 3 categories metals go into?
Metals, Non-metals and Metaloids
What is concentric cable transmission line?
It is a shielded high voltage cable made up of center conductor with the next layer being a semi-con layer followed by a insulation layer with another layer of semi-con wrapped with a copper stranded ground and covered by a protective jacket. It is usually three wires, each carrying a phase of the three phase primary that most power companies generate today.
What is the other name semi metals?
Semi-metals are also called metalloids.
Do semi-metals count as a metal?
Semi-metals, also known as metalloids, exhibit properties of both metals and nonmetals. While they have some metallic characteristics, they are not considered true metals. Instead, semi-metals are a distinct category in the periodic table.
Where is the location of semi-metals?
Semi- metals are placed in a zigzag pattern. They are also called metalloids.
Do semi metals count as metals or nonmetals in compounds?
NO
What property of semi-metals is useful in the electronics industry?
Semi-metals have free electrons which can conduct elecricity.
Is a semi metal hard?
Their hardness will be less than that of metals but more than that of non metals. Hence the name, semi metals or metalloids.
Can semi metal conduct electricity?
Yes, although they won't conduct it as well as regular metals. Semi-metals have characteristics of both metals and nonmetals.
Where are the semi metals in the periodic table?
Between the metals and nonmetal
Where can you find the semi metals on the periodic table?
The semi metals are called metalloids. They are present on zigzag line on periodic table.
What are the properties of Semi-metals or Metalloids?
Their properties are similar with non-metals and metals. That's why they're called semi-metals. They are reactive depending on the element they are reacting with, and they are semi-conductors.
What property of semi-metals are useful in the electronic industry?
semi-conducting
What are properties of semimetal?
Semi-metals have some properties of metals and some from nonmetals. Semi-metals are solid at room temperature. They are also brittle, hard, and somewhat reactive.
