“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

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

Captive power plants generate an additional 34.444 GW. Non Renewable Power Plants constitute 87.55% of the installed capacity and 12.45% of Renewable Capacity.[2] India

History of Clocks and the Impact of Electricity on them. Introduction: In this poster we are going to show you the history and the development of the clock through time and how it has impacted society. We will also show how electricity has affected the development and effectiveness of clocks. Sun clock: One of the first clocks on record is the sun clock. Sun clocks basically work on the principle that the position of a stationary object’s shadow will be in the same place at a certain

Static Electricity Everything is made up of tiny particles called atoms. The atoms are made up of even smaller parts called protons‚ electrons and neutrons. Protons have a positive charge (+)‚ electrons have a negative charge (-) and neutrons have no charge at all‚ they are neutral. Atoms normally have the same amount of electrons and protons‚ making them neutral and having no charge. When rubbing things together‚ electrons can move from one atom to another‚ resulting in some atoms having extra

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

Electricity and Magnetism Electricity Circuit symbols Potential difference The energy which is delivered to an electric circuit comes from the supply. The greater the potential difference of the power supply the more energy is delivered. Potential difference is measured in volts‚ which has the unit symbol V. Cells in series The more chemical cells that are connected in series the greater the potential difference that they supply. The potential difference of a number of cells connected

Electricity and Magnetism History Electromagnetism Originally electricity and magnetism were thought of as two separate forces. This view changed‚ however‚ with the publication of James Clerk Maxwell’s 1873Treatise on Electricity and Magnetism in which the interactions of positive and negative charges were shown to be regulated by one force. There are four main effects resulting from these interactions‚ all of which have been clearly demonstrated by experiments: 1. Electric charges attract

2 devices that use static electricity to funtion 1. Van de Graaff generator When the motor is turned on‚ the lower roller (charger) begins turning the belt. The belt is made of rubber and the lower roller is covered in silicon tape‚ the lower roller begins to build a negative charge and the belt builds a positive charge. Silicon is more negative than rubber so the lower roller is receiving electrons from the belt when it goes over the roller. The positively charged atomic nuclei‚ try to

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
