Yes, carbon has a negative temperature coefficient. -0.5*10^3/C
1 Ohm represents nearly no resistance to current flow, at all. The word, Ohm is usually capitalized as it comes from a person's name.
all the parts in the IC were made together so they have nearly identical characteristicsthe parts are close together in the IC so are probably at nearly the same temperature
Not long. It will burn out.
The temperature inside the internal combustion engine is approximately (300-400)'c because most of the cylinder manufactured by composition of aluminium alloy and other material.aluminium melting point was nearly the 652'c. so above this temperature it goes to the molten state.
Firstly turn of the power before this test...Using a resistance or continuity tester you should get the following results:Short circuit: Very low resistance (nearly 0 ohms) or the bell will ring.Open circuit: Very high resistance (Somewhere in the range of Mega ohms) or the bell will not ring.The reason for this is because and open circuit has a gap in it (which has high resistance).The short circuit has wires that are crossed and so has a really low resistance.
Porcelain is an insulator, its resistance approximates infinity.
Invar is a material that has a nearly zero temperature coefficient, meaning its dimensions do not significantly change with fluctuations in temperature. This makes it valuable for applications where dimensional stability is critical, such as in precision instruments and scientific equipment.
The basic principle of a Resistance Temperature Detector (RTD) is that the electrical resistance of a metal changes with temperature. Typically made from pure platinum, the RTD exhibits a predictable and nearly linear increase in resistance as temperature rises. This change in resistance can be measured and converted into a temperature reading using calibration equations. RTDs are known for their accuracy and stability, making them suitable for precision temperature measurements in various applications.
Platinum resistance thermometer requires a small current to pass through it to determine its resistance at different temperatures. Platinum has a linear resistance-temperature relationship; we can use this method to find the resistance at different temperatures.
A material that transmits nearly all the light in a ray because it offers little resistance to the light is called transparency.

Carbon.
very nearly anything.
A diamond is nearly pure crystalline carbon.
Mercury is commonly used in thermometers because it has a broad liquid temperature range (-39°C to 357°C), a high coefficient of expansion, and is a good conductor of heat. These qualities make it ideal for accurately measuring temperature changes.
No, carbon and carbon fiber are not the same. Carbon is a chemical element with the symbol C, while carbon fiber is a material composed of thin fibers made mostly of carbon atoms. Carbon fiber is known for its strength, light weight, and resistance to heat and corrosion, making it popular in industries like aerospace and automotive.
Pure carbon is one kind of element, which is one kind of pure substance.There are several materials that are formed from pure carbon, including:graphiteDiamond. Diamond is elemental carbon that has been exposed to high pressure and temperature for prolonged periods to form the crystal diamond carbon nanotubes(See the links below for other allotropes of carbon)Anthracite coal is nearly pure carbon.
