Basic Electronic Components

  1. Resistors

A resistor the flow of electricity through a circuits
Resistors have a set values..
since voltage, current and resistance are related through Ohm’s law, resistance are a good way to control voltage and current in your circuit..

Symbol Of Resistance

Resistor. rheostat (variable resistor). Potentiometer

More on resistors.

Resistor Color Codes.

1st band = 1st number

2nd band = 2nd number

3rd band = #of zeros/multiplier

4th band = tolerance

color code

2. Unit

Knowning Your units is important !

• Kilo and mega common in resistor.

• Milli micro nano & pico can be use in other components.

K (kilo) = 1000

M (mega) = 1,000,000

M(Milli) = 1/1,000

u (micro) = 1/1,000,000

n (nano) = 1/1,000,000,000 (one trillionth)

p (pico) = 1/1,000,000,000,000 (one quadrillionth)

3. Capacitors

• A capacitor Store Electrical Energy .
This pool of electron is available for Electronic Components to use ..
capacitance is measured in farads. Small capacitors usually used Electronics are often measured in microfarads

Symbol Of capacitor

Fixed Capacitor. Polarized capacitor. Variable Capacitor

some capacitors are polarized.

the different length terminal on 1 of the capacitors ..

Polarity of capacitors.

Polarity of capacitors.

• The shortest terminal goes on the negative side .

• stripe is on the negative terminal side of the capacitors..

4. Diode

•. An ideal Diode will have zero resistance in the reverse direction.

• A diode is a one way Valve for pass
A diode has low ( zero) resistance in one direction ,and high( infinity ) resistance in the others direction..

• Diode will protect your Electronics. projects

Diode Circuit Protection

• In a DPDT switch , if polarity is wrong, so the motor will run backwards• In an electronic circuits ,if the polarity is wrong , you can fry your components.A Diode in your system ‘ll help to prevent problems.

.

Diode have a bar on the cathode (negative) side.

Some Diodes Pic

5. Light

• light emitting diode (LED) is semiconductor .

Let me tell you about a new and very good software For Engineers

NextDFM PCB design Analysis Software Sometimes there are some problems with your PCB designs, after you have a prototype, some of them go wrong, then you are upset that where the mistake has happened, for this problem you need a software that makes those mistakes. Show us .

Features of the NextDFM software .

  1. Graphics are easy to read with this software so that you can ensure that all the necessary data in the file is correct or not.

2. Identify the wrong circuit in the design.

3. Next DFM help you in improve design quality, performance and reliability

4. Instant quote and billing options In Next DFM software

5. Save your Precious time .

I Hope you find this useful..

if yes, So like it, share it comment your any doubt
