In which of the following are choppers NOT used? Correct Answer AC voltage regulators

Choppers can provide regeneration, fast response, smooth control but do not provide AC regulation.

Concept:

A chopper is a static device which is used to obtain a variable dc voltage from a constant dc voltage source. Also known as a dc-to-dc converter.

They can step up the DC voltage or step down the DC voltage levels.

Types of Choppers:

  • Type A Chopper or First-Quadrant Chopper
  • Type B Chopper or Second-Quadrant Chopper
  • Type C Chopper or Two-quadrant type-A Chopper
  • Type D Chopper or Two-quadrant type-B Chopper
  • Type E Chopper or fourth-quadrant Chopper

 

Application of Chopper:

In electronics, a chopper circuit used in power control and signal applications.

  • It is used for DC motor control, solar energy conversion and wind energy conversion.
  • It is used in electric cars, airplanes and spaceships.
  • It also is used as power supplies in computer, commercial electronics, and electronics instruments.
  • Electric traction
  • Battery charging purposes
  • Mine haulers

 

AC voltage regulators doesn't use chopper.

Eight north Indian Ocean countries, namely, Bangladesh, India, the Maldives, Myanmar, Oman, Pakistan, Sri Lanka and Thailand, were asked to contribute names so that a combined list could be compiled. Each country gave eight names and a combined list of 64 names was prepared. This list is currently in use, and all cyclones arising in the north Indian Ocean are named from this list, with one name from each country being used in turn. Almost 38 or 39 names from the list have been used up, but since many cyclones dissipate long before they hit land, their names rarely figure in the papers or other media. The names that people do know about, and remember are, naturally, those that were most destructive ones, or very recent. Aila, in 2009 is remembered with a shudder for the enormous destruction it caused in West Bengal and Bangladesh; Phaillin, also for the damage it caused when it hit the Odisha coast in 2013. Two harmless cyclones, which also might remain in peoples memory, are the more recent ones of 2014 — Hudhud, which threatened the east coast of India and Nilofar, which was expected to, but did not, devastate the western coast. The names in the cyclone list are usually words one associates with storms; words which mean water or wind or lightning in various national languages. Sometimes they are names of other things — birds or flowers or precious stones. The name Aila, contributed by the Maldives means fire, the name Phaillin from Thailand means sapphire, the name Hudhud from Oman is the name of a bird, probably the hoopoe, and the name Nilofar, given by Pakistan, is the Urdu name of the lotus or water lily. The eight names suggested by India, and which are in the list of 64, are Agni, Akaash, Bijli, Jal, Leher, Megh, Sagar and Vayu, meaning in that order, fire, sky, lightning, water, wave, cloud, sea and wind. Five of these names (that is, up to Leher) have been used so far.
Which name suggested by India has not been used so far?

Modern civilization is completely dependent on energy, which has therefore to be abundant and also economical. About 85% of the world's energy is supplied by oil, coal and natural gas while nuclear, hydro, wind and solar power and biomass supply the rest. Coal, nuclear and hydro are used primarily to generate electricity while natural gas is widely used for heating. Biomass is used both for heating and cooking. The wind and solar power is the future's hope as they are sustainable energy sources. Oil powers almost all machines that move and that makes oil uniquely versatile. Oil powered airplanes carry 500 people across the widest oceans at nearly the speed of sound. Oil powered machines produce and transport food. Oil powered machines are ubiquitous. Clearly, we live in the age of oil but it is drawing to a close. According to data available if oil production remains constant until it's gone, there is enough to last 42 years. Oil wells will produce less as they become depleted, which will make it impossible to keep production constant. Similarly natural gas and coal will last another 61 years and 133 years respectively. Naturally, as they become scarce, they become expensive, leading to a worldwide energy crisis. If we are to survive on this planet, we have to make a transition to sustainable energy sources. The transition may be willy-nilly or planned - the choice is ours. The dawning era of limited and expensive energy will be very difficult for everyone on earth but will be even more difficult if it is not anticipated. It is of utmost importance that the public and policymakers understand the global energy crisis and act in tandem to ensure that the species 'homo sapiens' does not become extinct. Biomass is an energy source used in
10 people - A, B, C, D, E, P, Q, R, S and T are sitting opposite to each other in two different rows. There are five people in each row and facing towards each other. Q is not facing north is sitting opposite to the one who is sitting second to the right of D. S is an immediate neighbour of A but not of Q. P is not sitting at any of the extreme ends. R is facing north and is sitting at one of the extreme ends but not opposite to S. S is sitting in the opposite row of B but is not sitting opposite to D. Only one person is sitting between B and D. D and Q are not sitting at any of the extreme ends. C is sitting second to the right of E and opposite to the one who is an immediate neighbour of D.
