01․ Depletion region of a p-n junction is formed
During manufacturing process, the donor and acceptor atoms form the depletion region. It increases during reverse bias and decreases under forward bias.
02․ A 555 IC is used to produce
A 555 IC known as Timer-IC is used to produce clock of desired frequency by setting the values of certain capacitors.
03․ Doping in a semiconductor increases which quantity
Doping means adding impurity in semiconductor, which can be either from 3rd group or 5th group to form p type or n type respectively. It increases the conductivity of the semiconductor since it increases either holes or free electrons in the semiconductor.
04․ Donors to a semiconductor material is
Pentavalant atoms are of group 5, having 5 electrons in their outermost shell. Four electrons form covalent bond and the rest electron act as a free electron. So they act as donors to the semiconductors.
05․ Example of donor atom is
Group 5 elements are Donor type atoms. Antimony is a Group 5 element.
06․ Acceptors impurities are of ________ material
Acceptors are from group 3 and they always act as p-type material because they have 3 electrons in their outermost shell. The deficiency of one electron acts as a hole.
07․ Base-10 system is also called as
The number system has base 10 is called decimal number system. Decimal number system has 10 digits in it, from 0 to 9.
08․ Base of a number system is also known as
Base of any number system is called as radix.
09․ Binary Logic is mainly based on arithmetic operation and
Logical values are always handles with logical as well as arithmetic operations. Logical cases are like OR, AND, NOR, NOT etc.
10․ In a rectifier circuit, the diode converts
Diode converts alternating voltage to unidirectional current which is then converted in to voltage by load resistance connected across the output load terminal.
