RESISTORS

Resistors are used to limit current or divide voltage and in some cases, generate heat.

Used for driving circuit which requires low current and voltage than available.

A two terminal non-polar componentUnit of resistance is ‘Ω’.

Practical Use….• To reduce the current flowing in circuit, use resistance in

parallel.

• To reduce the voltage for any circuit, use resistance in series.

CAPACITORS

A two terminal electronic component which stores energy in form of charge.

Capacitance is a measure of a capacitor's ability to store charge.

Measured in Farads(F) µF or pF

Types of capacitors

Polarised: Specified +ve and –ve terminals

Non Polarised: No defined terminals

Practical use• Timer Circuits.

• Clipper & clamper circuit.

• DC filter circuits.

DIODES

• A two-terminal electronic component that conducts electric current in only one direction.

Types of diodes

• LED (Light Emitting Diode)Emits light when provided with power supply.

• Photo DiodeGenerates Current when it is exposed to light.

TRANSISTOR

• A transistor is a semiconductor device commonly used to amplify or switch electronic signals.

• The three terminals are Emitter, Base and Collector

Page 13: Basics of Electronics

• Transistor are of two types:

1-> n-p-n

A straight switch

2-> p-n-p

A inverted switch

Practically used…

• As a switch

• As an amplifier
