BASIC ELECTRONICS TUTORIAL4- COMPONENTS AND THEIR SYMBOLS PART2

   Hiii.........friends this is second part of  our last tutorial   BASIC ELECTRONIC TUTORIAL4- COMPONENTS AND THEIR SYMBOLS  , in this tutorial we are going to discuss about some more components ,their symbols and their uses. lets continue......


LOGIC GATES

AND 
If all the inputs of an AND gate are HIGH, then the output will also be HIGH. If any one of them is LOW, the output will also be LOW.

OR
 If any one of the input is HIGH, the output will also be HIGH. If both inputs are LOW, the output will also be LOW.

NOT
 

Also known as the inverter Gate. There is only one input for this gate. If the input is HIGH, the output will be LOW. If the input is LOW, the output will be HIGH.

NAND

Short form for NOT AND Gate. Of all the inputs are HIGH, the output will be LOW. If any one input is LOW, the output will be HIGH.

NOR

Short form for NOT OR. If both inputs are LOW, the output will also be LOW. For other cases, the output will be HIGH.

EX-0R

Short form for Exclusive NOR. If both inputs are either in LOW state r HIGH state, the output will be LOW. If both inputs are different, the output will be HIGH.

EX-NOR

Short form for Exclusive NOT OR. If both the inputs are the same, the output will be HIGH. If both are different, the output will also be different.

SWITCHES

Push Switch

This is an ordinary switch that passes current only upon pressing.

Push to Break Switch

The push to break switch is usually kept in the ON state (closed). It turns to OFF state (open) only when the switch is pressed.

Singe Pole Single Throw Switch

Also known as the ON/OFF switch. This switch allows the flow of current only when it is kept ON. Abbreviated as SPST.

Single Pole Double Throw Switch

Also known as the 2-way switch. It can be also called as an ON/OFF/ON switch as it has an OFF position in the center. The switch causes the flow of current in two directions, depending on its position. It can be abbreviated as SPDT.

Double Pole Single Throw Switch

Abbreviated as DPST. Can also be called as a dual ON-OFF switch. This is used to isolate between the live and neutral connections in the main electrical line.

Double Pole Double Throw Switch

Abbreviated as DPDT. The switch uses a central OFF position and is applied as reversing switch for motors.

Relay

is abbreviated as ‘RY’. This device can easily switch a 230 Volt AC mains circuit. It has three switching stages called Normally Open (NO). Normally Closed (NC), and Common (COM).

AUDIO AND RADIO DEVICES

Microphone

This device is used for converting sound to its corresponding electrical energy. Abbreviated as ‘MIC’.

Earphone

Does the reverse process of microphone and converts electrical energy into sound.

Loudspeaker

Does the same operation as an earphone, but converts an amplified version of the electrical energy into its corresponding sound.

Piezo-Transducer 

It is a transducer that converts electrical energy into sound.

Amplifier

Used to amplify a signal. It is mainly used to represent a whole circuit rather than just one component.

Aerial

This device is used to transmit/receive signals. Abbreviated as ‘AE’.   

So these are basic electronic components with their symbols and brief discription. I  hope this article was beneficial for beginners. in next tutorial we will discuss about some other basic electronic topics. If you have any doubt, question or critical comment please post here.
