Why don't Birds get Electrocuted on Power Cables?

Electricity is the flow of electrons through conductors. It always takes the easiest route, i.e., electricity always flows through a path of least resistance.

Now, the power cables through which electricity flows are made of copper. Copper offers least resistance and is a very good conductor of electricity. However, the bird's body offers greater resistance and is not a good conductor as copper. Hence, electricity ignores the bird and flows through the cables and birds don't get electrocuted. Besides this, electricity flows from its highest potential to its lowest. Now, the power cables usually run at different potentials. If bird's feet are on the same power cable, then they are at same potential. Thus, the bird doesn't get electrocuted. However, when the bird touches two cables with different potentials at the same time, then electricity will flow through the bird to go to the other cable with lower potential and the bird will get electrocuted.

How Energy conversion from coal is done?

Single generator sets of over 600 MW are now used in the UK, though there are many smaller generators in use. A 600 MW generator can supplythe average needs of over 1 million UK households. Three or four such generators are typically installed in a single large coal-fired station which isoften sited close to a coal mine, away from the city dwellers who consume the electricity. Such generators are usually driven by a compound arrangement of highpressure, intermediate-pressure and low-pressure turbines, increasing in size as the pressure decreases. Modern turbines rotate in a speed range from 1500 to 3500 r.p.m., usually 3000 r.p.m. for the UK’s 50 Hz system. For large coal-fired plant the steam pressure could be 25 megapascals (MPa) with steam temperatures of 500–600 °C to improve the thermodynamic efficiency. In nuclear reactors, which operate under less demanding conditions, the steam is superheated to about 5 MPa and 300 °C. Modern water tube boilers are complex and have ...

How ASPs works?

The Web and the Internet began to really heat up and receive significant media exposure starting around 1994. Initially, the Web started as a great way for academics and researchers to distribute information; but as millions of consumers flocked to the Internet, it began to spawn completely new business models. Three good examples of innovative models include: • Amazon - Amazon (which opened its doors in July, 1995) houses a database of millions of products that anyone can browse at any time. It would have been impossible to compile a list this large in any medium other than the Web. • Ebay - Online auctions make it easy and inexpensive for millions of people to buy and sell any imaginable item. It would be impossible to do this at a reasonable cost or in a timely manner with any medium other than the Web. • Epinions - Thousands of people contribute to a shared library of product reviews. One of the Web's greatest strengths is its worldwide view a...
