Nowadays, electronic components can be found in all of oour appliances,toold and devices. Ipod, PDAs, mobile phones, game consoles and kitchen appliances are designed using electrionic circuits and built with components.Electronics as a subject arouses curiosity even in young children because they want to explore things. They are often driven by curiosity making basic electronics for kids an enjoyable task. Children can be taught to create projects as part of application 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 has a starting point and an end point known as terminal. There are two kinds of terminals -positive or negative.Remember this simple concept: negative electrons seek positive electrons. Circuits dictates how and where electricity can flow. Not all Christmas light bulbs go dark in case one bulb is broken, isn’t it? That is a concrete application of how parallel circuits work. For that matter,there are various kinds of circuits,but the most frequently used are simple, series and parallel.
There are two types of currents : alternating current (AC) and /or direct current (DC). The main difference between the two is that a DC sends the electricity in a single direction. Classic example of this is a battery which has a head and a bottom that must be properly placed to work well. Residential homes have AC because each room must have power source for appliances. It is much better than DC where only the battery is used as power source. Avoid using a DC plug into an AC outlet.
Basically utilized to regulate the flow of electricity. You flick a switch to open the circuit electricity flows and the light opens. Similar to switches, the fuse is also used to regulate 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 controls the flow of electricity especially in consumer appliances. Normally,resistors are insulated with a rubber material. In the case of AC devices, inductors are used to change the current’s direction.
Basic electronics for kids is good because children can be induced to perform basic experiments.
