Question

Tungsten is a bad conductor of electricity
A. True
B. False

Answer 1

Hint: Conductor is an object or type of material that allows the flow of charge in one or more directions. Materials made of metal are common electrical conductors.

Complete step by step answer:
Tungsten is a lustrous and silvery white metal. This metal resists attack by oxygen, acids and alkalis. It has the highest melting point out of all the metals. Tungsten is used in filaments in incandescent light bulbs, it is also used in electric contacts and arc-welding electrodes.
It is also characterised by a uniquely low coefficient of thermal expansion.
It has the lowest vapour pressure of all metals, and at temperatures over ${{1650}^{\circ }}C$ has the highest tensile strength. It is attacked only slightly by most mineral acids.
Tungsten is a metal, and as all common metals it is also a good conductor of electricity. Also it is very hard and because of its high thermal stability and good conductivity properties it has many uses in electronic devices. So the above statement is true.
So, the correct answer is “Option A”.

Note: Tungsten is commonly used in heavy metal alloys such as high speed steel, from which cutting tools are manufactured. It is also used in the so-called 'super alloys' to form wear-resistant coatings.
Tungsten steel is used for manufacturing micro-drill bits, high-durability self-sharpening rotary cutting blades, and rocket engine nozzles, among many other applications. When the filament of the bulb which is made of tungsten is heated it due to the high temperature it conducts electricity.
