The terms conductor, insulator, semiconducting elements, donor impurities, acceptor impurities, n-type semiconductors, and p-type semiconductors has to be defined. Concept introduction: Conductor: A conductor is a material which allows the flow of an electrical current . Insulator: An insulator is a material which does not allows the flow of an electrical current. Semiconducting elements: Semiconducting elements are partially allows flow of an electrical current. Donor impurities: Conduction elements producing impurities are said to be donor impurities. Acceptor impurities: Impurities which are electron deficient are said to be acceptor impurities. n-type semiconductors: Solid semiconducting material having donor impurities are said to be n-type semiconductors, where “n” indicates negative which means the charge of the extra electron. p-type semiconductors: Semiconducting material having acceptor impurities are said to be p-type semiconductors, where p indicates positive.

Modern commercial airliners are largely made of aluminum, a light and strong metal. But the fact that aluminum is cheap enough that airplanes can be made out of it is a bit of historical luck. Before the discovery of the Hall-Héroult process in 1886 , aluminum was as rare and expensive as gold. What would happen if airplanes had to be made of steel? The fuselage of the Airbus A380, which can carry 575 passengers, is approximately a hollow aluminum cylinder without ends, 72.0m long, 8.4m wide, and 2.5mm thick (see sketch at right). The fuselage of an airplane Suppose this fuselage was made of steel (density 7.87/gcm3 ) instead of aluminum (density 2.70/gcm3 ), and let's say the average passenger has a mass of 83kg . We'll also assume the engines can't lift any greater mass than they already do. Calculate the number of passengers that the Airbus A380 could carry if its fuselage was made of steel.
