today ’s culture‚ electricity is a vital part of functioning as a society. Simple tasks‚ such as waking up at a designated time or enjoying a piece of music‚ are accomplished currently via electronic means. One only needs to consider the consequences of a relatively short power outage factories close down‚ phones and computers go dead‚ traffic slows to a crawl‚ food spoils in refrigerators to accurately observe how power-dependent our society has become. However‚ electricity is a constantly developing

I woke up and the bedroom was hot.I guess the power still hasn’t been fixed yet. It drives me crasy with no heating on a bloody winters day in the middle of December! I slowly slip out of bed still clutching my blanket for some warmth. I climb down the ladder and as soon as me feet touch the ground I quickly jump onto the carpet. The floor is like a sheet of frozen ice. No floor heating either. Great! Well‚ at least something can keep me awake in the morning at quarter to six. I’m just about to

Electricity is the set of physical phenomena associated with the presence and flow of electric charge. Electricity gives a wide variety of well- know effects such as lightning‚ static electricity‚ electro magnetic induction and the flow of electrical current. In addition‚ electricity permits the creation and reception of electromagnetic radiation such as radio waves. Electrical phenomena have been studied since antiquity‚ though advances in the science were not made until the seventeenth and eighteenth

Atomic Structure & Electricity 1. Draw an atom with an atomic number of 12. Label the protons‚ neutrons‚ and electrons. Use the periodic table to identify which atom you have drawn. 2. How many valence electrons are present in this atom? 2 3. Would this atom prefer to gain or lose electrons? Why? Lose‚ because the octet rule dictates that if there is less than 4 valance electrons‚ they would prefer to leave the atom. 4. Describe the differences between conductors‚ semiconductors

Hazards of Static Electricity; Lightning Lightning is a massive electrostatic discharge between the electrically charged regions within clouds or between a cloud and the surface of a planet. It is the sudden high-current discharge caused by the atmosphere’s electrical breakdown. Lightning is also one of the most deadly natural phenomena known to man. Lightning is an electric current; thus within a thundercloud up in the sky‚ many small bits of ice (frozen raindrops) collide into each other as

Background Electricity consumption is something we do out of habit and unintentionally. We develop our habits based on our needs‚ hobbies‚ works‚ entertainment and enjoyments. We never really aware of how much we use daily and how much the source of energy is left in this world. We are named as screen generation‚ it means we all depending on electronic stuffs to complete and help us out in our daily life. We use air-con‚ television‚ refrigerator‚ fan‚ lamps‚ iron more over we use electricity to charge

150 years ago‚ approximately around 1886‚ electricity was becoming a very exciting thing as AC plants started to appear all over the world. This meant great change for not only our establishments but also‚ for families that were near it and could afford it. It was the dawn of aluminum‚ cars and now a better way of life with electricity‚ life was about to get more exciting as well as easier for many families. Around the time of the late 1800’s‚ under the idea of “separate spheres”‚ caring for children
