Q:

The purpose of choke in tube light is

A) Induce high voltage B) Induce low resistance
C) Induce high resistance D) Induce low voltage
 
Answer & Explanation Answer: A) Induce high voltage

Explanation:

When the switch is ON, in a tube light choke is nothing but the coil/ballast ( inductor) which is used to induce the high voltage across it. as we know that inductor has property to induce high voltage for the brief period of time, this high voltage is required to ionize the gases in the starter.

Then gas inside the starter gets ionized due to this full voltage and heats the bimetallic strip that is caused to be bent to connect to the fixed contact. Current starts flowing through the starter. Although the ionization potential of the neon is the little bit more than that of the argon but still due to small electrode gap high voltage gradient is appeared in the neon bulb and hence glow discharge is started first in a starter.

As voltage gets reduced due to the current causes a voltage drop across the inductor, the strip cools and breaks away from the fixed contact. At that moment a large L di/dt voltage surge comes across the inductor at the time of breaking.

This high valued surge comes across the tube light electrodes and strikes penning mixture (mixture argon gas and mercury vapor).

Gas discharge process continues and current gets the path to flow through the tube light gas only due to low resistance as compared to the resistance of starter.

Q:

Read the passage carefully and choose the best answer to each question out of the four alternatives.


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 people’s 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?

A) Leher B) Agni
C) Bijli D) Vayu
