When a sample of germanium and silicon having same impurity density are kept at room temperature then resistivity of both?
Resistivity of silicon higher than that of germanium
Silicon has a relatively large latent heat of vaporization of 12800 Jg. This indicates that silicon has?
The boiling point has a high value.
What is the chemical name for H2SiO3?
SiO2 is a covalent network compound known as Silicon dioxide.
Does silicon have a high melting point?
Yes, it has a melting point of 1683 Kelvin.
Why does F1 driver suit made from silicon compound?
It has resistance to high and low temperature.
Why sheet steel with high silicon content is used in transformer core whereas lower silicon content sheet for rotating machine?
high permeability ,low hysterisis,increased resistivity
When a sample of germanium and silicon having same impurity density are kept at room temperature then resistivity of both?
Resistivity of silicon higher than that of germanium
Do wires that have high resistivity have high conductivity also?
No. In fact it is the opposite. Conductivity is the reciprocal of resistivity so a high resistivity means low conductivity. peace.
You do need to know the resistivity of silicon rubber Plzzzz some body help you?
That is not a solid value. Purity, moisture content and other fators come onto play. Silicon we use for isolation has very high resistive quailities. Over 11 Meg per cm.
Explain why arsenic-doped silicon conducts electric current better than pure silicon?
Pure silicon is intrinsic. It has a high resitivity which means it is a poor conductor of electricity in this state. The dopant that is introduced during the doping process can be arsenic, boron or phosphorous. These are the traditional choices to dope the intrinsically pure silicon. After the pure silicon becomes doped its electrical properties change. The main change is it has a lower resistivity and will conduct electricity. This is why silicon is called a semiconductor.
Does alumina become conductive at high temperatures?
Alumina is a good electrical insulator; at high temperatures the resistivity is smaller than the resistivity at room temperature.
5 properties of silicon are?
Thermal properties, 3. Wafer Flats. 4. Electrical properties, 4. Cleaving. - Resistivity & Mobility Calculator, 5. Silicon etching. 5. Mechanical properties
What are the charateristics of a N-type silicon?
The current carrier is electrons in the conduction band. The exact resistivity depends inversely on the quantity of dopant.
Is resistivity of a good conductor high or low?
It is Low
What are semi conducting substances?
Those which have resistivity in between conductors and insulators are known as semi conductors. Germanium and Silicon are very good examples of semiconducting materials whose resistivity of the order of 10 -2 to 10 4 ohm meter.
Why is the resistivity of a potentiometer high?
Because you touch yourself at night.
What property does the metal tungsten on an incandescent light bulb have?
it have high resistivity as well as high melting point. So due to high resistivity collision of moving electrons are taken place. It emits radiation which is appear as light.
