Now use the desi version of GPS- The IRNSS

Just after 35 years when US launched its Global Positioning System(GPS) 1st satellite, India has started sending satellites for its own version of GPS known as Indian Regional Navigation Satellite System(IRNSS). IRNSS plans to provide real time positioning and timing services in India and region extending up to 1500 km around India. Unlikely to GPS […]


How does sound gets amplified through a speaker?

Speakers contain an electromagnet: a metal coil which creates a magnetic field when an electric current flows through it. This coil behaves much like a normal (permanent) magnet, with one particularly handy property: reversing the direction of the current in the coil flips the poles of the magnet.Inside a speaker, an electromagnet is placed in […]

Sometimes the side of concrete bridges is observed to turn black in colour. What is the reason for this phenomenon?

The majority of such phenomenon, it is due to fungus or algae growth on concrete bridges. After rainfall, the bridge surface absorbs water and retains it for a certain period of time. Hence, this provides a good habitat for fungus or algae to grow. Moreover, atmospheric pollution and proximity of plants provide nutrients for their […]


Do you know, Google also produces CO2 (Carbon Dioxide)?

One Google search produces about 0.2 g of CO2. But since you hardly get an answer from one search, a typical search session produces about the same amount of CO2 as does boiling a tea kettle. Google handles about 1 billion search queries per day, releasing some 200 tons of CO2 per day. By Annapurna Mohanta, […]


Every Civil Engineer should know about BATS.

BATS: The Basics of Bridge Design If you’re going to build a bridge, you’ll need some help from BATS — not the furry, winged mammals that so often live beneath bridges, but the key structural components of bridge construction: beams, arches, trusses and suspensions. Various combinations of these four technologies allow for numerous bridge designs, […]


Some of the facts about electronics product…

1. 80 to 85% of electronic products were discarded in landfills or incinerators, which can release certain toxics into the air. 2. Cell phones and other electronic items contain high amounts of precious metals like gold or silver. Americans dump phones containing over $60 million in gold/silver every year. 3. Only 12.5% of e-waste is […]


Every electronics engineering should know basic functions of Electronic Devices.

Electronic devices perform three main functions: (1) amplification, (2) switching, and (3) oscillation, all as part of circuits. A circuit consists of a series of connected electron devices and other parts. By combining the three functions in various ways, engineers design electronic equipment that performs many other special functions, such as the high-speed operations of […]
