S19-Wk1: "Introduction to basic electronics "

Introduction to basic electronics reminds me of my secondary school days when I did an introduction to technology or as we normally call it introtech. It was a subject that taught me a lot about electronics and technology.

Today I wish to join the contest organized by this teaching team on the topic Introduction to Basic Electronics. Without delay, I wish to go straight into the topic of the day by providing answers to the questions given.

Workshop 1

For this question, we are to draw on paper the symbol of the following Alternating current, Direct current, Amperage, Resistance, Potentiometer or variable resistor, Rectifier diode, Zener diode, LED, Diode bridge, Electrolytic capacitor, Ceramic capacitor, Coil, Fuse, Transformer, Battery, Ground
NPN and PNP transistor and Motor.

We have a total of 18 items from the above list to draw and for that reason, I have decided to draw 9 items each on two papers making it a total of the needed items.

The image above shows the images and their names below each image for proper and clear identification as required by the question above.

Alternating Voltage: The word Alternating voltage which is commonly called AV is a type of voltage that changes with time in its magnitude and polarity. So this means that the movement of voltage here moves to and fro i.e. from and back and doesn't move only in one direction.

Direct Voltage: As the name implies direct voltage, is a type of voltage that moves only in one direction. This means that the movement of current or voltage here doesn't go to and fro instead it just moves without changing direction.

Resistance: The word resistance in electronics means opposition. So when there is an opposition to the flow of voltage we call that resistance. The unit for measuring resistance is ohms.

Potentiometer: This is a circuit that has three terminals and these three terminals include a resistor and moving contact the function of this terminal is to split the incoming voltage into two parts before it can be used by the receipt.

Rectifier diode: This an electronic device whose primary aim is to convert an alternating voltage to a direct voltage with the help of the PNP and NPN diode.

Diode bridge: In electronics, a diode bridge can be seen as the configuration of 4 or more diodes in a circuit. This means that to have a diode bridge, at least 4 diodes must be connected and this is to help in the effective transfer of voltage.

Capacitor: A capacity is an electronic device that is used to store electric charges. It is made up of two conductors i.e. positive and negative conductors.

Transistor: In electronics transistors act as a switch for the electric device that they are connected to. This means the transistor can be used to on and off i.e. change the signal of the electronic device.

Transformer: In electronics a transformer is a device that is used to transfer an alternating voltage or current from one circuit to another.

Fuse: A fuse in electronics is a device that is used to control the amount of voltage or current that is needed by an electronic device. So it saves as a protective element on an electronic device as it doesn't allow over or undercurrent in the device to affect it.

Lithium battery: This is a rechargeable battery that helps to retain energy and is used when there is no means to power up the electronic device. The battery in our phones and systems can be linked to the Lithium battery.

Workshop 3

Here I will be listing the different types of the following devices one after the other.

Resistors: There are two types of resistors and they are the linear and nonlinear resistors.

Capacitors: There are several types of capacitors i.e., electrolytic capacitors, ceramic capacitors, vacuum, film, paper, hybrid, polymer capacitors, etc.

Diodes: There are also many types of diodes and a few of them include zener, led rectifier, laser, pin, tunnel diode, etc.

Transistors according to their encapsulation: Include power transistor, chip transistor, surface-mount transistor, and peak-mount transistor.

Coils: There are two major types of coil and these are the copper coil and the hormonal coil.

Workshop 4

From the downloaded images below, I have labeled them using the alphabet from A because I couldn't write on it but I have provided names to the label places also below for your confirmation. So image one and the label can be seen below 👇

a = capacitor
b = Transformer
c = wire
d = capacitor
e = green cylindrical capacitor
f = coil
g = coil inductor
h = diode
I = resistor
j = bridge

Having finished with image 1 we move to image number 2o and their labels are also below 👇.

a = Surface-mount resistor

b = Integrated circuit (IC)

c = PCB markings

Conclusion

It is good to visit these again after a very long time. As I said earlier this topic reminds me of my earlier school days in the technical school because we had hands-on practical equipment. I want to finally invite a few friends to also join the contest if they haven't shared their entries yet. I invite @steemdoctor1, @suboohi and @ruthjoe.
