Electricity Essay Examples

Victor Frankenstein or his creature?

Which character does the reader have more sympathy for: Victor Frankenstein or his creature? The Modern Prometheus, more commonly known as Frankenstein, is a gothic novel about a scientist written in 1818 by Mary Shelley. It is a well-known tragic tale of a young scientist by the name of Victor Frankenstein who was intrigued by… View Article

The resistance of a wire

As we are dealing with electricity the power supply MUST be OFF before changing the wires or touching the Galvoltammeter.  A very likely mistake is to leave the electricity flowing for too long. The wire will soon heat and burn. To prevent this I should turn the supply off straight away. Fair Test It is… View Article

What affects the resistance of a wire?

The current must be kept constant and reasonably low so as to minimise the wire heating up because heat increases resistance. The wire must also be kept straight but not held too tight as the diameter will decrease and the wire will become longer which increases resistance. These two things must be monitored because otherwise… View Article

The resistance around a circuit

I predict that the longer the piece of wire, the more resistance there will be. I will keep the material, diameter, temperature and voltage being passed through it the same. I shall use nichrome wire and make it lengths of 100cm, 90cm, 80cm, 70cm, 60cm and 50cm and so on until 20cm. This way I… View Article

The resistance of the wire

The atoms take up more space so there is more chance of the electrons being caught by them; more energy is going to be lost as heat. As temperature increases so does resistance. If we increase the cross section there will be a bigger area, so more free electrons available for conduction. More free electrons… View Article

Electrical Conductors vs Insulators

Every thing in the world is differentiable on the basis of its electrical conductance. Some things are called insulators and these substances never conduct electricity. they include things such as cold air,wood and plastic. Then there are things that conduct electricity and current flows through them, they are called conductors. examples of conductors are most… View Article

Book Report on Pigeons at Daybreak

The story entitled “Pigeons at Daybreak” by Anita Desai of India is a representation of love and acceptance. Mr. Basu is the man who is unable to perform his task on his own because of the different illnesses that developed into his body. Otima, the wife of Mr. Basu has the selfless love towards him….

Service to Mankind

Not much over a hundred years ago, electricity, except in the form of lightning, was an unknown force. Its discovery was due to Michael Faraday, the great English scientist. On one occasion, about 1830, he was showing one of his early experiments to a distinguished company at the Royal Institution in London. He showed that… View Article

Costs of residential photovoltaic solar electricity

Abstract Now a day’s electricity is more important concern. We use a lot of home appliances which is operated by electricity but electricity we use; it is costly and not available every where. As we know sun is the source of energy, the energy which provided by the sun, less in cost, mostly available every… View Article

Sustaining the natural resources with Smart grid

It is easy to take electricity for granted but modern life would not be possible without it. To keep it going we need more efficient ways to manage electricity. For over a hundred years, coal and other fossil fuels have been used by power plants to produce the electricity we use every day. The grid… View Article

Understanding Electricity

The change in temperature of the water can make significant changes in the ecosystem and diversity of the marine life. More so, this can cause a ripple effect wherein the habitat, food source and natural aquatic cycle can be subjected to distress that can cause major alterations in the dynamics of the aquatic ecosystem. The… View Article

The History of Electric Transformer

Transformer is a device that transfers electric energy from one circuit to another, usually with a change in voltage. Transformers work only with a varying electric current, such as alternating current (AC). Transformers are important in the distribution of electric power. They raise the voltage of the electricity generated at a power plant to the… View Article

Electricity Generation Using a Wind Turbine

Wind turbines are machines built for generation of electricity. The electric power is generated by harnessing the wind speed to drive the shaft that connects to the gears assembled to amplify the amount of energy produced. Aside from wind power, other forces, like gravity and thermal energy, also affect the rotation of the blades, which… View Article

Electricity and its applications

Electricity is caused by net flow of charge across a cross-sectional area. The charge carrying species could be different in different conducting media. In metallic conductors current is due to net flow of electrons; in semiconductors the current is due to movement of conduction electrons and hole and in electrolytes the current is due to… View Article
