Electrical and Electronic Components in Electronics and Electrical Projects
In this Instructable I will be going over the basics components of Electrical Engineering as well as there biggest uses in the industry. Did you use this instructable in your classroom? Add a Teacher Note to share how you incorporated it into your lesson. Switches are one of the most basic electrical components but are also one of the most used in electrical engineering. A switch responds to an external force to mechanically change an electric signal.
Basically what this means is that when you push down or flick a switch you are allowing current to flow through to the rest of the circuit. The common light switch used in household wiring is an example of a toggle switch. Like the toggle switch, selector switches can either rest in any of their positions or contain spring-return mechanisms for momentary operation. A Diode is the simplest two-terminal unilateral semiconductor device.
It allows current to flow only in one direction and blocks the current that flows in the opposite direction. The two terminals of the diode are called as anode and cathode. The characteristics of a diode closely match to that of a switch. An ideal switch when open does not conduct current in either directions and in closed state conducts in both directions.
Zener Diode: The Zener Diode allows current in reverse direction when the applied voltage reaches the breakdown voltage. Based of principle of zener breakdown. This type of diode is especially popular and is most commonly found in small electronics stop street lights and we may even see it finding its way into house lighting being cheaper and more Eco friendly. Constant current diode: It is also known as current-regulating diode or constant current diode or current-limiting diode or diode-connected transistor "mouth full".
The function of the diode is regulating the voltage at a particular current. It functions as a two terminal current limiter. In this JFET acts as current limiter to achieve high output impedance. The resistor is a passive two pole component used to limit the amount of current that is allowed to flow at any given time as well as the voltage.
An electric battery is a device consisting of two or more electro-chemical cells that convert stored chemical energy into electrical energy. Each cell has a positive terminal, or cathode, and a negative terminal, or anode.
The terminal marked positive is at a higher electrical potential energy than is the terminal marked negative. These are especially handy when it comes to designing portable devices. Now there are many different kinds of batteries such as lead acid or AGM batteries but i wont get into it to much as it doesn't really change the concept of the battery.
All you need to know is that a battery cell can store a charge a release it at a later point without deteriorating too much. A capacitor is a two-terminal, electrical component used to temporarily store a charge in an electric feild. This is use full in Electrical Engineering because it can be used to smooth out varying DC supplies aswell as filtering circuits high pass, low pass or band pass they are even used as temporary batteries.
Transistors are is a small mostly 3 pole component made of elements in the group 4 in the periodic table, Silicon being the most common. To understand it think of it like this, Your brain has billions upon billions of neurons. The neurons let you think and remember things, Computers act the same way except the computers neuron is called a Transistor.
The transistor acts either like an amplifier Taking a small electric current at an input current and then produces a much bigger output current, you can see this at work in hearing aids or microphones or like a Switch taking a small current flowing through one part of a transistor can make a much bigger current flow through another part of it.
Basically the small current switches on the larger one, this is how a computers chips work. A Potentiometer is a knob that has variable resistance which can result in the dimming of your lights or even sending information back to your micro controller this component normally has 3 poles also called a 3 pole resistor it works in the same way as a voltage divider except for the fact that this has variable outputs. You will often find these in house holds or sound controllers.
Motors is a device that converts direct current into mechanical power. They rely on the forces produced by magnetic fields. It does this by having a coil of wire with a current running through it generates an electromagnetic field.
The direction and magnitude of the magnetic field produced by the coil can be changed with the direction and magnitude of the current flowing through it. DC motors : This Motors simply starts spinning if you give it DC connection the speed and direction all depends on the arrangement of the positive and negative poles as well as the amount of current you put through it.
Stepper Motors: The main difference between them and all the other motors, is the way they revolve. Unlike other motors, stepper motors does not continuously rotate Instead, they rotate in steps from which they got the name. Each step is a fraction of a full circle. This fraction depends mostly from the mechanical parts of the motor, and from the driving method. Reply 4 years ago on Introduction. Reply 4 years ago. Reply 2 years ago. Thank you!
As a dopey dentist, this is exactly the thing I need to be able to get started on something I have always wanted to do, but didn't know a switch from a capacitor. Forever grateful. As someone who considers themselves "electrical illiterate", this was a great post, very easy to understand.
I'll definitely be reffering back to this in the future! Thanks for taking the time to do this. Question 1 year ago on Introduction. Trying to id this component, part of power supply section for instrument cluster VFD. Finding different voltages on the terrminals between working and non working boards. I've been fixing some electronic modules since a while, but all i do is visual inspection on the components that looks broken and change those.. A great instructable and very informative.
One query though? Doesn't a capacitor store a charge in the form of static electricity? I may be wrong I'm only a beginner!

Hey Everyone In this Instructable I will be going over the basics components of Electrical Engineering as well as there biggest uses in the industry. I will also give brief instructions on where to find and salvage them. Add Teacher Note. We have many different kinds of switches the most common are - Toggle Switch: Toggle switches work by connecting and disengaging two pieces of metal within the switch.
An ideal switch when open does not conduct current in either directions and in closed state conducts in both directions There are many different types of diodes the most common are: Zener Diode: The Zener Diode allows current in reverse direction when the applied voltage reaches the breakdown voltage.
You can find these in pretty much any portable device. The most common types of capacitors you will find are: - Supercap: Also known as a ultracapacitor, as the name implies these capacitors have very large amounts of capacitance. The most common types of motors are DC motors : This Motors simply starts spinning if you give it DC connection the speed and direction all depends on the arrangement of the positive and negative poles as well as the amount of current you put through it.

Most home builders find importing materials from China a good idea. These wholesale building materials are taken in at very cheap prices to be used by construction firms and a number of US retailers. A lot of industries today are making really good business coming from their deals with building materials suppliers in China. Such success has contributed to increased demands for an outsourced home building materials company overseas.

Where conductors entered a wiring device such as a lamp or switch, or were pulled into a wall, they were protected by flexible cloth insulating sleeving called loom. The first insulation was asphalt-saturated cotton cloth, then rubber became common. Wire splices in such installations were twisted together for good mechanical strength , then soldered and wrapped with rubber insulating tape and friction tape asphalt saturated cloth , or made inside metal junction boxes. Knob and tube wiring was eventually displaced from interior wiring systems because of the high cost of installation compared with use of power cables, which combined both power conductors of a circuit in one run and which later included grounding conductors. At present, new knob and tube installations are permitted in the U.
Download Summary. This application note defines each of these attributes and should make the answers clearer. While the emphasis is how these parameters relate to Power Knot products, the principles apply equally to any physical machine. If I turn it on for ten seconds, the power it uses at any time during those ten seconds is 1 kW.
