Welcome to ABC of Electronics!
Every effort is made to keep the website up and running smoothly.We must understand the basics of electronics because if basic concepts are not grasped it will get difficult to proceed. Hence to make it easier This Electronics Tutorial is divided into 4 sections, Section 1, Section 2, Section 3 & Section 4.
SECTION 1
Electronics is the flow of electrons which we call as charge through semiconductors.
Electric Current is the flow of charge.
Electronics Symbols with their meaning.
SECTION 2
Digital Logic Gates: Work of a logic gate is to perform a logical operation on one or more logic inputs and give us a single logic output. This logic is called Boolean logic. Logic gates are generally applied electronically using transistors or diodes. In electronic logic, a logic level is represented by a voltage or current. Below are given the gates used in electronics.
The AND gate is a logic gate that gives an output of '1' only when all of its inputs are '1'.
The OR gate is a logic gate that gives an output of '0' only when all of its inputs are '0'
The NOT gate is a logic gate that gives an output that is opposite the state of its input.
The NAND gate is an AND gate with a NOT gate at its end
The NOR gate is an OR gate with a NOT gate at its end.
In XNOR The output is high when both inputs A and B are high
In XOR The output is LOW when both inputs A and B are high
Now let us see what are capacitors, resistors, diodes & transistors in electronics circuits and what are their applications.
