Describe Electrostatics In Nature Lightning ?
Man has always been curious about and often awed by the power of lightning> Benjamin Franklin’s experiment approximately 200 years ago with a kite in which showed that lightning consisted of the same type of electricity that could be produced on earth by electrostatic means is possibly the most famous study made of lightning . Although this phenomenon has been the topic of considerable research, scientists have failed to agree upon the cause and the nature of lightning.We know that lightning is a violent example of the tremendous electrostatic charges that can occur in nature, but there are several different explanations given about the manner in which the charges that cause lightning are produced in a cold. Most of these theories are built upon the premise that because of violent air currents in cloud, and the interaction of ions and water droplets and ice [articles, positive negative charges are produced in a cloud and are then separated with the positive charges moving upward and the negative charges moving downward.To understand this generalization, let us first look at the makeup of a thunderhead clod. In the “mature” stage the cloud top will reach up to 10,000 to 15,000 m (40,000ft) where the temperature is about -50°C. within this cloud, which may have its lower layer at a height of 5,000 ft and a temperature of around +20°C, there are strong updrafts reaching a speed of 60 mi/h. the water vapor in the cooled below its freezing immediately until it has a “seed,” or nucleus, to form upon, and as a result it becomes super cooled.However, once ice starts to form, with crystals grow rapidly and fall through the rising air causing a down draft of cold air. When this cold air reaches the bottom of cold air. Reaches to the ground just ahead of the rain, causing the sometimes noticed chill that rain, causing the sometimes noticed chill that precedes a rainstorm. Let us consider the most popular theory that the lighter “spray like” parts of the torn off darning falling becomes positively charged and are then carried upward into the cold upper layer of the cloud. The heavier particles become negatively charged and continue to move downward and in so doing acquire more negativity as they grow in size.
