“IF THERE IS NO ELECTRICITY” To think of life without electricity is almost impossible today. Elec tricity provides all the comforts of life. We find ourselves completely helpless and feel its importance whenever power fails or when the sup ply is irregular. We curse the government for its failure to supply unin terrupted electric supply. In case of no electricity our life would be totally different. We will have to use earthen lamps‚ lantern or candle-light instead of electric bulbs and tubes

What is Electricity? Electricity is one of the most powerful forces in our lives. As a matter of fact‚ it can even kill you. The most vital part of electricity is called electric energy. This is what we commonly think of when we hear the word electricity. “Electricity” reminds us of anything that we plug into an electrical outlet in order to make it work‚ such as lights‚ refrigerators‚ video games‚ microwaves‚ and computers. Scientists discovered ways to produce electric energy in large amounts

Electricity’s impact on Society Electricity has had multiple impacts on society both positve and negative. Electricity has had an effect on everyone in the world‚ even though some people have no understanding or have no use for electricity. For example‚ there are tribes in the Amazon who have never seen a lightbulb who have never beared witness too the heracy of Big brother and yet they are still effected by electricity. The chainsaws which cut down their beloved forests are designed by a man called

Lightning - Each bolt can contain up to one billion volts of electricity - Electrical discharge is caused by an imbalance between positive and negative charges in the atmosphere - Colliding particles of rain‚ ice‚ or snow increase this imbalance and often negatively charge the lower reaches of storm clouds - Objects on the ground‚ like steeples‚ trees‚ and the Earth itself‚ become positively charged - A step-like series of negative charges‚ called a stepped leader‚ works

History of Electricity Our knowledge of electricity has started from very humble beginnings when you look at where we are today. Electricity has been around for as long as humans have. When lightning strikes ancient people may not have understood what it was or why it happened‚ but they at the very least witnessed it happen. Nature acted as a sort of catalyst to spark the curiosity of early people. It was only until sometime between 624 BC and 546 BC where an understanding of electricity began to

Early History of Electric Power Date Event Pictures 1800-1819 Early electric experiments were performed with DC. In 1800‚ Alessandro Volta published a description of a silver/zinc battery‚ acknowledging that he did not know how it worked. In 1807‚ Humphry Davy constructed a practical battery (the picture will be immediately familiar to anyone who works with UPS systems)‚ and demonstrated both incandescent and arc light. • Volta’s famous bi-metalic frog twitch (I did this one myself as a boy..

Electricity‚ what a wonderful advancement that was invented throughout history. If there wasn’t electricity we wouldn’t be able to power our cars‚ turn on our stoves‚ plug our phone chargers into the wall socket or even be able to turn on our artificial light when it’s dark outdoors. Electricity has made a huge impact on our lives. Most people don’t realize how different the world would be if Benjamin Franklin never started his kite and key experiment. The world may have never evolved into the world

we call Electricity. Electricity is the flow of electrical power or charge. It is both a basic part of nature and one of our most widely used forms of energy. It is actually a secondary energy source‚ also referred to as an energy carrier. That means that we get electricity from the conversion of other sources of energy‚ such as coal‚ nuclear‚ or solar energy. These are called primary sources. The energy sources we use to make electricity can be renewable or non-renewable‚ but electricity itself
