Which Of The Material Has Positive Temperature Coefficient Of Resistance
A positive temperature coefficient (PTC) is a type of electrical resistance that increases with temperature. The phenomenon was first observed in the 1800s by Thomas Johann Seebeck, who noticed that the resistance of a wire increased as its temperature increased. Positive temperature coefficients have many applications, but they are especially common in electronics and power systems.
Carbon is a good conductor of heat, but not as good as copper. It has a positive temperature coefficient of resistance.
Silver is a good conductor of electricity, but it has a positive temperature coefficient of resistance. This means that as the temperature increases, the resistance of silver increases. Silver can be used for thermistor sensors because it will increase its electrical resistance when heated up.
Germanium is one of the most common materials used in semiconductors. It has a positive temperature coefficient of resistance, which means that as the temperature increases, so does its resistance. This is important for devices like transistors and diodes because it allows them to function properly at high temperatures (upwards of 200 degrees Celsius).
Germanium also has a negative thermal expansion coefficient; this means that as germanium expands under normal conditions (or contracts), its volume remains constant while other materials expand or contract more than they would otherwise. This property makes germanium ideal for use in microwave devices such as radar systems and satellite communications equipment
The positive temperature coefficient of resistance is one that increases with increasing temperature. Silicon has this characteristic, which means that it will increase its resistance with increasing temperature.
On the other hand, a negative temperature coefficient of resistance decreases with increasing temperatures and vice versa
Carbon nanotubes are a type of material with a positive temperature coefficient of resistance. They’re used in the construction of supercapacitors and batteries, as well as lighter-weight, higher-strength materials.
Carbon nanotubes are one of the most promising materials for use in electronics. They have a high electrical conductivity, low thermal conductivity and good mechanical strength. In addition to these properties, carbon nanotubes also have a positive temperature coefficient of resistance (TCR).
