This document provides information about basic electronics concepts. It defines voltage as the potential difference between two points, and current as the flow of electric charge carriers. It explains that alternating current switches direction regularly, while direct current flows in one direction. A rectifier converts AC to DC, an inverter converts DC to AC, and an uninterruptible power supply allows computers to run briefly during power outages. Control systems use electronic devices like sensors and actuators to regulate other systems and are used in various industries like manufacturing, power plants, and water treatment. Control systems can be open-loop, without feedback, or closed-loop which uses feedback automatically.

2. WHAT IS VOLTAGE ?
WHAT IS CURRENT?

3. VOLTAGE IS GENERALLY FOR OPEN LOAD:
Voltage, also called electromotive force, is a
quantitative expression of the potential difference in
charge between two points in an electrical field
CURRENT IS GENERALLY CLOSED LOAD:
Current is a flow of electrical charge carriers

4. WHAT IS ALERNATIVE CURRENT?
WHAT IS DIRECT CURRENT?

5. Alternating Current (AC) is a type of electrical current,
in which the direction of the flow of electrons switches back
and forth at regular intervals or cycles. Current flowing in
power lines and normal household electricity that comes
from a wall outlet is alternating current
Direct current (DC) is the unidirectional flow of electric
charge. Direct current is produced by sources such as
batteries, thermocouples, solar cells, and commutator-type
electric machines of the dynamo type. Direct current may
flow in a conductor such as a wire, but can also flow
through semiconductors, insulators, or even through a
vacuum as in electron or ion beams.

6. BASICS ELECTRONICS
BUT DIFFERENT
WHAT IS RECTIFIER?
WHAT IS INVERTER?
WHAT IS D/B INVERTER & UPS?

7.  A rectifier is an electrical device composed of one or more
diodes that converts alternating current (AC) to direct current
(DC)
INVERTER:
 an apparatus which converts direct current into alternating
current
UPS:
 An uninterruptible power supply (UPS) is a device that allows
a computer to keep running for at least a short time when the
primary power source is lost. It also provides protection from
power surges

8. DIFFERENCE B/W:
 UPS LEVEL OF CAPABILITY IS LOW
&
 INVERTER LEVEL OF CAPABILITY IS HIGH

9.  GENERALLY EVERY PERSON USED FOR
ELECTRONIC IN OUR LIFE
MAJORLY THE ELECTRONIC ITEMS
 RESISTOR
 CAPACITOR
 INDUCTOR
 TRANSISROR
 IC
THAT ARE MAJOR PART IS USED

10. • THIS MAJOR COMPOUND IS USED SOME
MORE INVENTION ARE PRODUCED
• AGRICULTURE
• COMPUTER
• WASHING MACHINE
• HOSPITAL FIELD
AND ALL FIELD IS USED FOR THE ELECTRONICS

11. MAJORLY USED THE ELECGRONICS
HOW TO CONTROL THE ELECTRONICS
CONTROL SYSTEM

12. What is control system?
A control system is a set of mechanical or
electronic devices that regulates other devices
or systems by way of control loops.
• Different type field is used for the control
system:Definitioncontrol system
• scada for indusrial control system.
• Control systems are used to enhance
production, efficiency and safety in many
areas, including:
• Agriculture etc.

13. • Chemical plants
• Pulp and paper mills
• Quality control
• Boiler controls and power plant
• Nuclear power plants
• Environmental control
• Water treatment etc
)

14.  TYPE OF CONTROL SYSTEM?
 OPEN CONTROL SYSTEM
 CLOSE CONTROL SYSTEM

15. APPLICATION:
 OPENLOOP CONTROL SYSTEM:
NOT AUTOMATIC
EG: WASHING MACHINE ETC.
CLOSELOOP CONTROL SYSTEM
AUTOMATICALLY
EG: INDUSTRIAL FOR SCADA
MANUFACTURING FOR IC,RESISTOR,
TRANSISTOR ETC.

16. AT FUTURE ALL THINGS ARE AUTOMATICALLY IN
OUR LIFE
“SCIENCE AND TECHNOLOGY WAS DEVELOPED IN
EVERY DAY
ONWARD TO PART OF DEVELOPMENT
IN TECHNOLOGY FOR EVERY PERSON”
