Hello students, in this question we are asked to describe the general principles of electrical and electronic fitting techniques, the purpose, function and the components of such systems.
00:13
So, electrical and electronic fitting techniques involves installation, assembly and connection of various components to create a functional electrical and electronic system.
00:24
So, we can just take an example of an electronic system.
00:30
So, we have wiring and connections that connect between a cell and the electric source, electric source and the connections.
00:39
We will have switches, we will have resistors across, right, this could happen and then the switches will turn on and turn off the system, the cell will provide the current source for the system and then we have resistors which resist the flow of electric current, they are used to control the current levels, voltage drops and protect the components from excessive current.
01:12
Switches regulate the on -off conditions and it will provide certain parallel and perpendicular or parallel and series arrangements enabling, right.
01:25
So, that is another thing and then we have capacitors.
01:28
So, the capacitors store and release electrical energy, it can be used for filtering, timing, energy storage, coupling etc.
01:36
So, this is capacitor, this is resistor, it's r1 and r2, this is switch number one, this is cell, okay.
01:45
So, capacitors are identified by their capacitance values measured in farads or micro farads.
01:52
So, it indicates their, it also can be indicated their voltage range, ranging or rating can be described in that demonstration.
02:03
So, resistors, what they do, we understood, capacitors what they do, we understood.
02:08
Now, we will have something called inductors in the system.
02:13
Inductors can also be there.
02:17
So, what inductors does is that inductor stores energy in the form of magnetic field, right.
02:24
So, the inductors can be used for applications such as filtering, energy storage and inductive load control...
