43/64

Most of the

electronics devices

are made fromsemiconductor

materials

R i

Resistor

DiodeTransistor

Integrated circuit (IC)Microprocessor

They are made from semiconductormaterials

ELECTRICAL CHARGES


47/64

The language of Electricity

VoltageCurrent

Resistance

V l


48/64

What is Voltage?

Ans. the emf or the pressure thatpushed the current to flow

Wh t i t?


49/64

What is current?

The movements of freeof electron thru

conductor.


50/64

What is a resistance?

Ans. An opposition, limitthe flow of Current


51/64

As switch is OFF, bulb doesnt litethere is no current flow.


52/64

As the switch turn-on,bulb will light Current flows in


53/64

As the resistoris connected in series w/the bulb

It Act as the opposing current, bulb goes dimmer.

4 Oh L


54/64

4. Ohms Law

Voltageandcurrentisdirectly Proportional, &

inversely proportional toResistance.


55/64

Electronics devices arecomplex and complicated,They are connected in one

of two ways.

5. Electronics Circuit

Th i nn ti n


56/64

The series connection

They are a group of componentsconnected Together end to end.

P ll l C i


57/64

Parallel ConnectionThey are a group of components

Connected together in a common terminal


58/64

Electronics Devices

Electronics devices are

classified intoActive and passive

A ti i t bl f


59/64

Active is a components capable of

controlling voltages and current or

ability to amplify and rectify.

Ex. 1. Diode2. Transistor

3. IC or microprocessor


60/64

Passive is a component that

does not provideamplification.

Ex. 1. Resistor

2. Capacitor


61/64

Breaker


62/64

Question?


63/64

1. Define voltage & current?

2. In ohms Law, what is therelationship of voltage, current

and resistance?3. Explain semiconductor devices.

4. Differentiate the active andpassive device.
