Introduction: Electricity generation in the UK. In 2006/7 the UKs electricity consumption reached 48 000 GWh or about 1.3 × 1018 joules of energy. This energy is supplied to about 28 million consumers,

Hello, dear readers. In my last post, which can be read here, I explained the radioactive sources inside the earth and world energy sources. Some of the world energy sources discussed are electrical power,

Radioactive elements have a chemistry which tended to make them oxidize in the young Earth: they formed compounds whose density made them float to the upper layers of the molten Earth, to be concentrated

There is now little doubt that the average global surface temperature is on the increase. What is less certain is how much of the increase is caused by human profligacy, as we consume increasing amounts

A warm greeting to my great friends and readers. In my last post, I discussed about the simple amplifier, maximum power theorem and its derivation, properties of operational amplifiers and their uses.

We are all familiar with audio devices such as radios and CD systems. An audio amplifier is an important part of all of these systems. The amplifier takes a small, weak signal and makes it stronger. A

INTRODUCTION When pop groups perform on stage, they no longer have to put up with a clutter of wires and speakers because of the progress made in electronic sound engineering. Singers and musicians cannot

Greetings, everyone. This is a follow-up on a series of posts I started some months ago on Communication physics, where I discussed the growth of the internet and mobile phone network. In those series

Interest in superconductors was reinforced in 1987 when a superconductor with a transition temperature as high as 92 K was discovered. It is a material that has the approximate formula Yba2Cu3O6.5 and

The transistor was invented in 1951 by John Bardeen, Walter Brattain, and William Shockley, at the Bell Research Laboratories in the USA; It is used very widely as a controllable switch. Soviet KT315b

Suppose an electron needs energy E to escape from its surroundings, and that this energy is supplied thermally. The temperature T (in kelvin) multiplied by the Boltzmann constant k indicates the amount

In 1948, Wiliam Shockley filed a patent for his new invention, the junction transistor. He had combined the theory of quantum mechanics from earlier in the century with the fast-growing knowledge of new

Hello, everyone. This is a continuation from where I stopped in my last post on THE PHYSICS OF ORDINARY MATTER #4 and it will also be the last post on the series as well. In this post, I will be demonstrating

Greetings to everyone. Sequel to my last post on ORDINARY MATTER #3, this new post will explain how to determine the structures of crystals, structures of other solids, and finally on the ideal gas equations.

Greetings to the community and the entire world. Still on ordinary matter physics; today I will be discussing the different types of bonding in solids and liquids and also on crystal structures. IONIC

Greetings to you all. Still on the physics of ordinary matter and changing the state of a substance. I will start today’s discussion by explaining the dependence of melting and boiling temperatures on

Solid carbon dioxide, called dry ice because it vaporises at -78 °C without first melting, has being in use as a cleaning agent to strip paint, oil and grime from machinery parts. Equipment like a sandblaster

Greetings to all my readers and everyone in general. Starting from where I last stopped in my post on Oscillations and Mechanical waves. In this post, I will explain how to set up stationary waves and

So far in my previous post, we have assumed that there is no friction in our oscillating systems. However, in reality, this can never happen – there will always be some friction, causing energy to be lost

In simple harmonic motion, the displacement varies sinusoidally with time – and this is a lot more complicated than if displacement were linear with time. The figure below shows the displacement for an
