“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

How does water temperature affect the amount of dissolved oxygen? Ⅰ. Introduction Dissolved oxygen is just one of the many ways to measure water quality. It means the volume of oxygen that is contained in water. The amount of dissolved oxygen in water usually determines the quantity of organisms living in that water. Dissolved oxygen levels vary by how much oxygen the water can hold‚ how much oxygen is produced by photosynthesis‚ and how much oxygen is consumed by respiration. If water is too warm

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

Electricity generation is the process of creating electricity from other forms of energy. The fundamental principles of electricity generation were discovered during the 1820s and early 1830s by the British scientist Michael Faraday. His basic method is still used today: electricity is generated by the movement of a loop of wire‚ or disc of copper between the poles of a magnet.[1] For electric utilities‚ it is the first process in the delivery of electricity to consumers. The other processes

Activity: Drips and Leaks Water Use in the Industrialized World If you’re like most people in the developed world‚ you don’t think much about water. Clean‚ drinkable water is delivered into your residence almost invisibly‚ and it’s always there when you turn on a faucet. As such‚ most North Americans don’t see the need for water conservation‚ particularly those who live in
