Q. A tourist, who plans to visit a hill station located at very high altitude also wishes to take along his Television Set. In this context, consider the following:
LCD TV
Plasma TV
Cathode Ray Tube TV
Which among the above are expected to work properly at very high altitudes? Answer:
1 & 3
Notes:
LCD TV - Will work properly at high altitudes. LCDs use liquid crystals and do not depend on air pressure, so altitude does not affect their functioning.
Plasma TV - May have issues at high altitudes. Plasma TVs use noble gases that can be impacted by lower air pressure at high altitudes. They may not work properly.
Cathode Ray Tube TV - Will work at high altitudes. CRT TVs use vacuum tubes rather than gases so altitude does not impact their functioning.
