Document Summary
Answer: the air in the cabin of an air craft at high altitude can be very dry, which is suitable to build up the static charge. [it is similar to the effect we sometimes experience at home (with tv screen, door knob etc. ) in cold dry winter air. It is harmless, but it can give us a nasty jolt. ] A fire or an explosion may occur due to excessive build-up of electric charges produced by friction. Example: electric charges accumulate on an aircraft during flight. A preventive step may be taken to avoid such hazard which is written below. In the case of air craft, the tyres are made of slightly conductive rubber so that the large amount of charge build up on the body of the aircraft during flight can be discharged harmlessly during touch down. The electroscope was the first electrical measuring instrument. The first electroscope was pivoted needle invented by william gilbert around 1600.
