From this PPt you will know that basic components usages and working and how it is used in PCB Designing.

1. BASIC ELECTRONICS DEVICES IN PCB
DESIGNING

2.  Resistor
 Capacitor
 Transistor
 Diode
 Switch
 LED

3. Resistor
 Resistor is an electrical component that reduces the electric current.
Units : ohms (symbol: Ω)

4. Low Power Resistors High Power Resistors
& Rheostats
Types of Resistors

5. Resistors Color Codes

6. Capacitors
 A capacitor (originally known as a condenser) is a passive two-
terminal component used to store electrical energy.
Units: microfarads ( uF or mfd)
or Pico farads (pF)

7. Types of Capacitors

8. Capacitors Color Codes

9. Transistors
 A device composed of Semiconductor material that amplifies a
signal or opens or closes a circuit.

10. a – Bipolar , b - FET, c - MOSFET, d - Dual gate MOSFET,
e - Inductive channel MOSFET, f - Single connection transistor
Types of Transistors

11. Diode
 Current passing through a diode can only go in one direction called the
forward direction.

12. Types of Diodes

13. Switches
 A device for making and breaking the connection in an electric
circuit.

14. Types of Switches

15.  A light-emitting diode (LED) is a two-lead semiconductor light source.
It is a pn-juntion diode, which emits light when activated
