12th Physics Online Notes Conductor and Insulators

12th Physics Online Notes Conductor and Insulators 

CONDUCTORS:
Conductors are the device having a conductivity greater than 103 s/cm. Basically, electrical properties of any material depend on electronic population inside an atom as conduction is the result of the motion of electrons within the bands. In case of conductors, the conduction band is almost full and conduction band overlaps with valence band hence there us full conduction or full flow of electron from one band to another. Even at low temperature, it results in higher conductivity.

SEMICONDUCTORS:
Semiconductors have conductivity for silicon (it can range from 10-5S/cm to 103S/cm). Their conduction is almost empty and valence band is almost full, the energy gap between the conduction band and valence band is around 1eV. Their no such elements like semiconductors occurs naturally they are formed by doping in insulators. At the high temperature, they start conducting.

Why is Hindi Day celebrated on 14 September?

Why is Hindi Day celebrated on 14 September? After independence, the Government of India set a goal to give an ideal form to the mother tongue of the country and set a target for grammar and orthography using the Devanagari script to bring standardization in writing. Subsequently, on September 14, 1949, the Constituent Assembly decided by a vote that Hindi would be the official language of India. To propagate the importance of this decision and to spread Hindi in every region, India is celebrating Hindi Day every year from 1953 to 14 September, at the request of Rashtrabhasha Prachar Samiti, Wardha. Apart from this, 14 September is also the birthday of Rajendra Singh, who worked tirelessly to make Hindi the official language of India. Hindi Day is observed every year on 14 September to mark the importance of the Hindi language in the country. The Hindi language is one of the oldest languages, which derives most of its academic vocabulary from the Sanskrit language written in the Deva

Magnetic and non-magnetic material Class 6 Science

Magnetic and non-magnetic material  Class 6 Science A magnet is a substance that is drawn to certain magnetic materials like iron, cobalt, and nickel. Magnets have the ability to draw iron to them. Natural magnets are rocks that naturally draw iron. Non-magnetic materials include things like wood, rubber, coins, feathers, leather, etc. that are not drawn to iron. Magnet characteristics It pulls magnetic materials, such as iron. The magnet's two ends are referred to as its poles. The magnet's diametrically opposed poles are drawn together. Heating, hammering, or dropping causes it to lose its characteristics. On the basis of properties types of Magnets Temporary magnets are those magnets that are magnetic for only a little duration. Typically, iron, cobalt, or nickel are used to make them. When they are close to the powerful magnet, they act like a magnet. When they are yanked away from the powerful magnet, they stop being magnetic. Permanent magnets are magnets that have magne
