Water droplets in the air act as a conductor of this charge. Question 2. As a result of this process, the positive charges collect near the upper edge and the negative charges accumulate near the lower edge of the cloud and also near the ground. Lightning Conductor is a device which helps in protecting the building from the effects of lightning. https://finalfantasy.fandom.com/wiki/Lightning_(Final_Fantasy_XIII) Lightning is observed as a bright streak of light during a thunderstorm. Lightning is always accompanied by the sound of thunder. During a rain, the air currents move upwards and water droplets (in the form of rain) move downwards. Question-46 :- (Electricity Part-B Class-8th Concise ) How is a tall building protected from damage due to lightning? This causes the charges flow to the earth and the body looses the charge. Lightning is a massive electrostatic discharge caused by unbalanced electric charge in the atmosphere. It may strike as far as 10 miles from any rainfall. Question 1. This discussion on What is lightning Related: NCERT Solutions - Some Natural Phenomena? These charges flow to meet, thus producing strikes of lightning and thunder. Question 1. The conductor which is fixed on the top of the building to protect the buildings from the damage by lightning. Observations: a) i am cc'ed during it as much as the target which is lethal, b) it is easily interrupted by others, c) easily broken with cc-breaking abilities, d) never ever does 6 sec - lucky if it does 3 secs - no idea why. …, eoa-zboj-esa o n l y g i r l w a n n a T o s e x c h e t​.
