Resistor

Resistor is an electrical component that reduces the electric current.

Units : ohms (symbol: Ω)

Low Power Resistors High Power Resistors

& Rheostats

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)

Types of Capacitors

Capacitors Color Codes

Transistors

A device composed of Semiconductor material that amplifies a

signal or opens or closes a circuit.

a – Bipolar , b - FET, c - MOSFET, d - Dual gate MOSFET,

e - Inductive channel MOSFET, f - Single connection transistor

Types of Transistors

Diode

Current passing through a diode can only go in one direction called the

forward direction.

Types of Diodes

Switches

A device for making and breaking the connection in an electric

circuit.

Types of Switches

A light-emitting diode (LED) is a two-lead semiconductor light source.

It is a pn-juntion diode, which emits light when activated
