Electricity and its Importance to the Modern World

In today's world, it would seem unimaginable to live without electricity. What would man do without television sets, computers, music devices, and other modern equipment which use electrical currents? How about air conditioners, refrigerators, electric fans, heaters, ovens, and various household appliances? Most men would be lost and helpless. Of course, sometimes, there are those who want to "escape" for a while and go back to nature sans these modern conveniences. But those are just temporary respites.

However, man was only able to use electricity in the 1800s when Alessandro Volta invented the first battery. He gave the world its first continuous source of electric currents. Thereafter, it was discovered that electric currentscould be used to produce heat, light, chemical action, and magnetic effects. This discovery led to various developments in the use of electricity which paved the way to the invention of numerous electrical devices and equipment which modern man now fully enjoys.

But how was electricity discovered? The word "electricity" comes from the Greek word electron, which means amber. It was the Greeks who discovered that when amber was rubbed, it was capable of attracting bits of cork or paper. This attraction later roused man's curiosity and interest which led to more discoveriesin the course of time.

As man continues to enjoy the use of modern equipment, maintaining electric power has become an essential part of this convenience. This is where electricians come in. To install the wiring and control the equipment through which electricity flows in our homes, businesses, and industries, we need electricians. The Bureau of Labor Statistics of the U.S. Department of Labor estimates that around 79 percent of electricians either work in the construction industry or are self-employed. Some Penn Valley electricians belong to private companies serving all sectors of society.

Electricians mostly focus on either maintenance or construction. The former are those who fix and upgrade existing electrical systems and repair electrical equipment. The latter install wiring systems in factories, businesses, and newly-built homes. Most electricians, however, do both types of work. A Penn Valley electrician is generally competent in both maintenance and construction projects.

The majority of electricians acquire their skills through apprenticeship which lasts for about four years. This apprenticeship combines on-the-job training with classroom instruction. Most states require electricians to be licensed. However, licensing requirements vary from state to state. In this connection, most Penn Valley electricians are not only trained to provide the best service possible, they are also duly licensed with skills backed by years of experience.
