good morning Sir, been busy with my clearance so that I can go for service next month. I will be checking on every morning.

Moving forward, let's explain what happened in this water supply scenario
In the case of pumping water direct to the tank without a buffer tank, note the following
1. Fluctuations in the water supply due to pump operation is transmitted to each flat ( No constant flow)
2. There is no pool of water created
3. Water distribution is not uniform
4. The moment the pump stops, the flow stops
Looking at the second scenario, the following is obtainable
1. Because there is overhead reserve, there is no fluctuations in the water flow
2. A big pool of water is created
3. The distribution is uniform
4. Continuous water flow even when the pump stops until the whole stored water is discharged.

Please any objections to these assertions?

ytdivine:
In the above example, we dealt with water flow, let's consider signal flow in a circuit.
Do you know that motion in a television is a multiple of images(continuous image flow). What happen when the motion is fluctuating? Do you know the source of our power supply (NEPA) fluctuates like the water flow from the pump. If this happens, you find out that the images from your TV set keep dancing and in S-Shape form. This is a practical illustration which you may have noticed.
Television is used here for example, this is the case for all the electronics.

Capacitor is a storage tank ( buffer) that stores electric charges(water) in an electric field(water pool/swimming pool)

The following should be noted
a. Charging and discharching (filling and offloading tank)
b. Energy storage (water storage)
c. Source of electric field ( water pool).

So when an electric signal passes through a capacitor, it absorbs the signal until its full and now acts like a new supply source providing a better signal flow(filtered signal). Capacitor is a mini battery in a circuit.

I hope I have not confuse anybody

ytdivine:
The next component which is the foundation of our programming is
INDUCTOR.
Our PLC programming language is Ladder Logic Language. This language is based on Relay Logic. Relay is based on Inductor. So pay maximum attention here.
What is PLC?
During interview season, you get amazed by response from job seekers.
There is a computer that control all industrial activities. This computer is called PLC, meaning programmable Logic Controller.
In advance electronics, you talk about Microprocessor and his elder brother, microcontroller. From this, you get Controller (computer). The one you can program or manipulate a lot is PLC.
Hope the point is clear

ytdivine:
As a punishment for not doing my assignment, the following students should come to the front of the class and kneel down
Zealousayo, bestbiz17, eddyboy, new username, micros
You can stand up and get to your seat once you do your assignment.

Southboy:
If I get you correctly, electric signal is used to charge the capacitor?
Can the device work when the capacitor is not fully charged?

Newusername:


Good evening boss. It's not like that oo. I have been busy. I will be doing all your assignment tomorrow.

ytdivine:

You're forgiven but make sure you participate very well

Let's take a step further, these signals are used in control functions. Very soon, we shall look at control.
Electrical or electronics systems are built or designed to allow various electrical signals to pass through them. In electronics, there are small small components that makes up the electronics units. Each components behaves differently when these signals pass through them.
Let's take this illustration.
Consider three men
Mr A
Mr B
Mr C
Let's simulate them with a slap (Signal)
You will find out that each of them react differently.
Reactions
Mr A : May God bless you
Mr B: a doubled returned slap
Mr C: collapsed
You can see from this illustration that the responses are different even though there were all subjected to the same input signal ( slap)
In engineering, we call it transfer function.
This is another foundation, if we get this point very clear, we will not have problem understanding relay logic which will eventually transform to Ladder Logic.
We shall consider two energy storing electronics components and see how they respond to electrical signal
a. Capacitor
b. Inductor

ytdivine:


Yes, not my fault. When people respond to my question, it shows am not dealing with ghost hence more energy for me to dish out information.
I have made myself available, people should draw as much knowledge as possible from my over 15years hand on the job industrial experience

Rome was not built in a day. A journey of 1 mile begins with a step. This journey of skill acquisition is a gradual one. Get serious with it. Little by little, you're there

Well done boss,

Thank you for this mentorship class, I hope students and young grad will take advantage of this class seriously because, what he is trying to dish out to you free of charge here, somebody spent #800,000 to 1 million to get this from an institute.


I am an electrical engineer by the way and I know what it's like to be a resource person in a department.

Hopefully, I would be able to contribute to this as the class progress.

Kudos to Oga "ytdivine"

What do you know about an inductor. What happens when
a. ac current
b. DC current
Passes through it

Thanks for the compliment. I said it before that young graduates and students will not appreciate this golden opportunity. Its only those working in industries that knows the value.
This is my own contribution to national development
