ELECTRICITY?
What is it? Can you touch it? It is a form of energy. During the stone age or before that, it did not exist. But today, it is used evveryday. If it is checked around the world, there is electricity being used every second. In the stone age, light came from fire, but today there are light bulbs. Electricity has its uses. Without electricity, it will be very difficult to survive. But, it has forms and names as well as properties. Some examples of electricity are electric charge, electric current, electric field, electric potential and electromagnet.
Electricity is very useful. For example, it can be used as a means to convert a form of energy to another. Electricity is a form of energy, which can neither be destroyed nor be created, but it can be from other forms of energy or be converted to another energy form. Electricity is a very important element in technology. A lot of the things like machines that were used fifty years ago, are now working faster with the same amount of electricity.
Electricity can also be used improperly, like when a bulb is lit, it is using electricity and converting it to light and heat energy, but when it is left, the electricity is just being wasted, instead of using it when it is required. So, by saving electricity or using it only when it is required can be very beneficial. Thus, electricity is a big part of technology.
