Why Electricity And Basic Electronics Are Inseparable



electricity and electronic
Aside from those powered by dry cells, all of our gadgets,devices, tools and equipments nowadays run using electrical energy. Everything from mobile phones, kitchen appliances and even electric cars, can not run without electricity. At the same time, these things are composed of electronic components that work together to provide people entertainment or functionality. Indeed, electricity and electronics are inseparable. Electronic devices depends on electricity to operate. Certainly, the best model of mobile phone is useless without any power!

Magnetism, electricity and electronics

Science teachers have taught us that electrons move around atoms actively. All of these movements are caused by electrical charges. These charges posses their own electric and magnetic fields. You now see the crucial role that magnetism plays in electronics. When electricity and electronics are discussed, it is inevitable to discuss magnetism. For example, electricity must flow through insulated wires made solely from rubber. Rubber is a type of material that can be used to coat wires so electric current can be conserved within the wires. Also, this serves as protection from any short circuit should wires come in contact with each other.

An electrical fields is another concept that people interested in electronics must understand. For every electric charge, an electric field surrounds it with a magnetic field counterpart. These fields are not visible to the naked eye but devices can used to measure them.

Wattage in relation to electricity and electronics

Watts is another relevant concept in electricity and electronics. A watt is basically defined as the International System unit of power equal to one joule per second. A very practical sample would be the wattage settings that determines the radio's loudness or softness. Nonetheless, appliances that have high wattage requirements can increase your electric bill. A louder radio volume setting equates to higher power consumption. Hence, having knowledge about watts, electricity and electronics can benefit you as a consumer. You may opt to look for more energy efficient appliances so that you can balance power and economy.

Understanding basic electricity principles greatly increase your knowledge of how electronic devices operate. Having familiarity with such electronic concepts can greatly help you as a consumer or as an electronics enthusiast.

How To Explain Basic Electronics For Kids

Basic Electronics For Kids
Almost all of our devices and consumer appliances are composed of electronic components. Ipod, PDAs, mobile phones, game consoles and kitchen appliances are designed using electronic circuits and built with components. Electronics is an interesting subject especially for young children who wants to know how things work. They are often driven by curiosity making basic electronics for kids an enjoyable task. Children can be taught to create projects but they need to learn some concepts in basic electronics for kids. Start using teaching these simple concepts:


Circuits

The circuit is like a train track that must be followed by the train. Electricity flows through the circuit which starts at one terminal and ends in another one. There are two types of terminals - positive or negative. Remember this simple concept: negative electrons seek positive electrons. Circuits dictate how and where electricity can flow. Not all Christmas light bulbs go off in case one bulb is busted. That is an illustration of how parallel circuits work. In fact, there are many types of circuits, but the most common ones are simple, series, and parallel.

Currents

There are two different types of currents: alternating current (AC) and /or direct current (DC). The main difference between the two is that DC sends the electricity in a single direction. Case in point, a battery has two ends that must be correctly placed with their right pole to make it work. Houses often use AC because anything can be placed into a socket anywhere for power. When DC is used, the battery is the main power source limiting its application. Never put a DC appliance into an AC outlet.

Switches

Primarily used to regulate the flow of electrical power. You touch a switch to open the circuit, power flows, and the bulb lights up. Aside from switches, a fuse complements switches in regulating the amount of electrical current flowing in a circuit. Once there is overload detected, the fuse blows to safely protect the wiring from fire hazards.

Resistors and inductors

These devices also monitors the flow of electrical power particularly in consumer appliances. Generally, resistors are insulated with a rubber coating. In the case of AC devices, inductors are used to change the current's direction.

Basic electronics for kids provides an interesting venue for young people to bring out their creativity.

A Guide On Different Types of Basic Electronics Components


Basic-Electronics-Components
An electronic device or appliance is composed of different parts known as electronic components. These basic electronics components are assembled together using a circuit diagram to create a device, tool or appliance. A computer's CPU is made up of basic electronics components that are connected with one another. It all begins with a circuit board or mother board (CPUs) that holds all the components together. An electronic circuit has a purpose to fulfill inside a device. For example, radios typically have amplifiers to increase volume.

There are two major types of basic electronic components. There is passive as well as active components. Here is a more distinct description of the two categories:

* Passive components are ones that do not provide net energy into the circuit they are connected with. It is also improbable for such to depend upon a power source except for the AC circuit that is attached to them. Eventually, they can not amplify (increase the power of a signal), although they may well increase a voltage or current that can be done by a transformer or a resonant circuit. Two-terminal components like resistors, capacitors, inductors, and most types of diodes are classified as passive components.

* Active components mainly depend on an energy source coming from a DC source; also, they can inject power into a circuit although this is not their main function. This includes amplifying components such as transistors, triodes, vacuum tubes(valves), and tunnel diodes. One of the most basic electronic components that solid state electronics can't do without are resistors.

Usually, there are three main parameters for resistors, yet solid state electronics would only need two parameters in many cases.

* Resistance - the value of resistance, measured in Ohms.

* Power - The amount of power the resistor can safely handle. Too much power will cause the resistor to overheat and fail.

* Voltage - This is not commonly indicated but it shows the maximum voltage across a resistor. It is a measure of the maximum voltage that may appear. If you have a background in basic electronics, as well as basic electronic components, you can use your skill in practical applications like building your own radio.

A Beginner's Guide To Basic Electronics Circuits

basic-electronics-circuits
Having some knowledge about basic electronics circuits is a practical choice. To begin with, all of our appliance and consumer electronics run on electrical power. Basic electronic circuits can help you understand simple problems such as why a light switch does not work at all. Besides, there are cases when an electrician is not available; thus, instead of waiting, you can apply what you learned in basic electronics circuits. In the same manner, you save money by doing it yourself.

A good understanding of basic electronic circuits requires familiarizing one's self with terms and concepts. You must be aware of the fact that electricity can also harm you if not properly handled. In order to learn safely and effectively, familiarize yourself with the following concepts:

Circuits - This concept has similarity to a circle in terms of flow of energy. The circuit is the path where electrons go through beginning from one terminal and reaching another end. The terminal can either be positive or negative. The flow happens using a single direction- negative to positive. Keep in mind that negative electrons are attracted to positive electrons; indeed, opposites attract.

Conductor - This is made up of a material where electrons can pass through. Usually, copper is used because it has high conductivity. Transmission between terminals is enhanced due to high-conductivity.

Insulator- From the term itself, it protects the conductor ( copper wire ) by wrapping it with a material such as rubber. No doubt, live wires are dangerous which is why they are insulated. Insulation coats the conductor.

You must also understand that there are two types of circuits: series and parallel. A series circuit is much simpler than a parallel one because electricity can only flow in one direction. A good example of this are light bulbs that stop working as soon as one bulb gets busted. This illustrates how a series circuits work. Conversely, electricity can possibly flow in two or more paths in parallel circuits. Thus, you would see some of your Christmas light bulbs working even if some of the bulbs are busted. A basic series circuit is often used for wiring the lights in our home. A lot of complex consumer appliances use parallel circuits because it's more stable. Nevertheless, consult an electronics repairman or electrician in case the trouble is complicated.
