There are many devices, which help appliances
to work for us and this are called ‘Electronics’. Such as - Capacitor,
Transistor, Diode, Resistor, Fuse, Filter, Battery
Different electronics do different type of
task. All the electronics are in-link through system-board. This process of
building an appliance through electronics is known to be 'Technology', where
theories of science being used to make electronics plus appliances.
This basic electronics are essential parts of
a appliance, such as - Computer, Mobile, Television, Refrigerator,
Air-conditioner, Vacuum cleaner, Dish-washer, Washing machine, Oven etc. Even
the ceiling fan has also this electronics.
Besides, all the appliances we use today need energy to
work. Electricity is the most common energy source for all appliances.
Electricity is actually the flow of electrons. Electricity can be produce in
many ways. What is, to produce electricity we need energy too. At past,
electricity commonly produced by windmill. At present, oil and gas are common.
Some electronics work without electricity, but oil or gas as energy source.
Some advanced countries use sunlight or garbage as fuel to produce
electricity and/or machines or appliances. Garbage is produce hugely everyday
all over the world. Now this is as fuel i.e. source of energy will be of a
great knock. Many countries take forward step to make it true. In near future,
we can be blessed by this.
