Correct Answer: Yoke
Explanation:
Twisting the yoke will tilt the picture. A projection color television uses three picture tubes and yokes for red, green and blue light.
Correct Answer: 1880s
Explanation:
The IEEE (Institute of Electrical and Electronics Engineers) was formed in 1963 by the merger of the Institute of Radio Engineers (IRE, founded 1912) and the American Institute of Electrical Engineers (AIEE, founded 1884).
Correct Answer: Stimulated emission
Explanation:
The word "laser" is actually an acronym for light amplification by stimulated emission of radiation. Atoms or molecules of the active medium that have been excited to a higher energy level are stimulated by a passing photon to relax to a lower energy level and emit a photon that is indistinguishable from the passing photon, thereby increasing the number of photons like the incident one.
Correct Answer: System file
Correct Answer: 25 thousand volts
Explanation:
This voltage often remains in storage even if the set is unplugged. Although the voltage is very high it has very low power but it can be dangerous because your body jumps if brought in contact.
Correct Answer: Remote control
Explanation:
Some authorities are recommending TV's, VCR's and Stereo's be connected to power strips with switches and turned off when not in use to save energy. Your remote will not work until power is switched back on.
Correct Answer: Alan Turing
Correct Answer: Transformer
Explanation:
The transformer is used to transform a medium voltage supply to a low voltage supply, e.g. from 11 000 V to 400 V. A transformer is rated in kVA, kilo-Volt-Amps, which is a measurement of electrical power.
Correct Answer: 2:3
Explanation:
The National Flag of India is a horizontal tricolour of deep saffron [kesaria] at the top, white in the middle & dark green at the bottom in equal proportion. The ratio of width of the flag to its length is 2 to 3. In the centre of the white band of the Indian National Flag, there is a navy blue wheel which represents the chakra. Its design is that of the wheel which appears on the abacus of the Sarnath Lion Capital of Ashoka. Its diameter comes close to the width of the white band & it has twenty four spokes. The design of the National Flag of India was adopted by the Constituent Assembly of India on 22 July 1947.
