World's Largest Electric Light Bulb- 50,000 and 75,000 Watts respectively

Image
    World's Largest Electric Light Bulb source Facts all about the world largest , longest, biggest, and tallest bulb. Imagine if we have this in our home maybe we cannot afford to pay the monthly electric bill because of the high wattages. World's Largest Light Bulb The Thomas Edison Memorial Tower and Menlo Park Museum was built in 1937 to mark the "Birthplace of Recorded Sound" in the Menlo Park section of what is now the town of Edison. Tallest Light bulb of Thomas Edison It sits on top of the 117-foot concrete Memorial Tower, which was built in 1937 by Edison’s employees. It’s an homage to both the light bulb and another key Edison invention, the phonograph.A monumental replica of Edison’s first practical incandescent bulb, it’s nearly 14 feet of Pyrex glass segments. Thomas Edison Longest Lasting Light Bulb Is the Centennial Light located at 4550 East Avenue, Livermore, California. It is maintained by the Livermore-Pleasanton Fire Department...

IRNSS vs GPS – Difference between IRNSS and GPS

Image
IRNSS(india)vs GPS(america) We will do the complete detail analysis of both IRNSS vs GPS system. We will differentiate both the system on several factors as the date of introduction, accuracy, range, the number of satellite cost and much more. So, let us find out which one is better IRNSS or GPS? GPS is Global Position System introduced by the United States. GPS is the world’s first position system. It has a total of 31 satellites. It is one of the important factors to find out the better system. Well, GPS has introduced 38 years ago in 1978 while IRNSS is introduced this year 2016. If we analyze this data then, we can easily rate GPS over IRNSS. IRNSS was first launched on 1st July 2013 to 28 April 2016. GPS was first launched in February 1978. First and final date of the launch was not released due to the cold war. Number of Satellite Launches of IRNSS vs GPS The number of launches tells the number of the satellite launched by the system. It also shows the life and dependencies o...

Make your own LED Resistor Selector Dial

Make your own LED Resistor Selector Dial.   1.The theory behind the LED Resistor Selector Dial   The Theory Behind this make LEDs are diodes with very specific characteristics. The most important values that must be followed are the (maximum) forward voltage [Vf] and the (maximum) forward current [If]. Typically, an LED powered with a voltage equal to Vf, will allow a current equal to If to pass through. The forward voltage of LEDs depends on the material they are made of (thus the color that they emit) and the number of diodes in series they have. For example, a red LED typically operates at 20mA when a voltage of 2.2 volts is applied across its leads.  So, what happens if we have 5 volts to power this 2.2V LED? There are many different LED drivers, but the simplest one is to use a resistor in series. Here is the typical circuit:     The idea of the resistor is to generate a voltage drop across its leads. Byselecting this resistor properly, the voltage...
