Hint: We know that sparking is a natural phenomenon that occurs due to the accumulation of charges. Lightning is also an electric spark but on a large scale. Benjamin Franklin was an American scientist who showed that lightning and the spark of our clothes are the same phenomena.
Complete step by step answer:
Let’s discuss when we observe a spark in an electric post. We have seen sparks when wires of the pole become loose. The spark is very common when a blowing of wind shakes the wire. We also observe sparks when a plug is loose in its socket. The spark is also seen due to heavy rain and thunderstorm.
So, the correct answer is Option D.
Additional Information:
When we rub a scale in our dry hair, the scale can attract small pieces of paper. This indicates that the scale got charged due to rubbing. So, we can say that by rubbing we can charge an object. Here, the comb is the charged object. The generated charge on rubbing cannot move, that means, they are static. The moving of charges constitutes an electric current. So, we can say that the current is nothing but a motion of charges. The electroscope is a device that is used to check whether an object carries a charge or not.
Note: Lightning is also an electric spark that is produced during the time of a thunderstorm. During a thunderstorm, there is an upward movement of electric current and downward movement of water droplets. This movement causes charge separation. The charges accumulated in different layers of charges. The meeting of positive and negative charges produces bright light (lightning) and sound. This process is termed electric discharge.
