Some of us may be skeptical about the tick-tick sound heard from the cars’ indicator or turn signal. 
Have you ever heard how this sounds? We may be skeptical about the turn-talk sound that the cars 
are indicator or the signal. How did this sound? There is no reason why some manufacturers are
 trying to reduce this volume of cars as new version releases.. Bye-metallic sprinkler in the laser
 is simply  makes the sound click-click on the indicator as it is heated and cooled
Before explaining this, the history of indicators will be interesting. By the early 1920s,
 there were different mechanical indicators signaling in cars. But the sound of the tick-tick sound
 you hear is in the early 1930's.
Joseph Bell patented the first electrical device that flashed — and then in 1939,
 Buick introduced turn signals as a standard feature.. By the late 1930s, American 
car maker Buick regularly started flushing turn signals in their cars. Similarly, 
other car makers followed the similar procedure. By 1950, the indicator / turn signals
 were forced into cars. From that point onwards, this voice is accompanied by indicators.

Thermal style flashers used to drive electricity to the indicator bulbs. By-metallic sprinkler
 in the flashlight is used to power the bulb into small intervals. The click-click sound on the
 indicator is the result of the heat and cooling of the spring.

. But the sound continued even from the thermal style floors and the electronic style
 flashersElectronic-style flashers are due to click-click sound and hese flashers work through a small chip.

LOW LOSS CONDUCTOR CABLE An answer to high T&D losses

In the process of supplying electricity to consumers, technical losses occur naturally and consist mainly of power dissipation in electricity system components such as transmission and distribution (T&D) lines, transformers, and measurement systems. T & D losses have I2R losses as a major component, and if one can reduce the resistance,the losses can be reduced.So, while resistance depends upon metal area and its resistivity,there is a need to improve both without changing the physical area of the conductor. This is besides improving compaction % i.e. Metal area/Physical area. Also, normal compacted conductors have a compaction of 87-91% causing a limit on metal area that can be fitted inside the physical area. These issues have been sorted by a unique design using 2 layers of trapezoidal wires. The electricity sector in India had an installed capacity of 205.34 Gigawatt (GW) as of June 2012, the world's fifth largest. Captive power plants generate an additional 31.5 GW.…

Power Theft-will it build darkness in India?

India, the largest democratic country of the world, provides shelter to more than 1.25 billion people. It is home to three times the population of the US though geographically only one third of it. The infrastructure has been developed enormously since its independence in 1947 but, even now many villages do not have electricity. Uninterrupted power is dream for most of the population. In this scenario, strange it may sound about 132 Billion units of electricity is pilfered in India during 2011-12. About 70% of population of India still lives in rural areas where agriculture provides the main livelihood to the majority. Many people do not have electricity supply and even when it is available, supply of electricity is erratic. When a utility starts providing 24 hrs power supply to certain area, it finds a major place in the newspaper. The Ministry of Power, though announced ‘Electricity to all by 2012’ as its objective, could not achieve it so far and now extended…

Why power theft in India is a complex problem?

Film Review Why should I be scared of the government when electric current doesn't scare me? asks Loha Singh, who purloins electricity and provides illegal connections for a living in Katiyabaaz (Powerless), a riveting new documentary on power theft in India. Singh, an irascible young man with a gift for invective, is the pivot around whom the film rotates. He snaps off and mangles wires to the main public supply cables for a pittance to provide electricity to scores of homes in a decaying city. His grateful customers regard free electricity as a right or buy stolen power because they cannot afford to buy it. One of the most poignant moments in the film is when Singh returns to his fragile mother in their crumbling family home and she implores him to "leave this dangerous job" and do something honourable for a living. Singh's eyes well up in a moment of self-realisation of his bleak and hopeless life. Loha Singh is, at once, the hero and villain of Katiyabaaz. Intro…
