The bold figures from the equation suggest the vector mother nature in the power, along with the unit vector r̂
The electric eel, Electrophorus electricus Electricity will not be a human invention, and should be noticed in a number of forms in character, notably lightning. Many interactions acquainted on the macroscopic stage, which include touch, friction or chemical bonding, are because of interactions between electric fields within the atomic scale. The Earth's magnetic discipline is because of the normal dynamo of circulating currents inside the Earth's core.
Since the cloud discharges, significant portions of positive (or occasionally destructive) charges operate from the air from floor to cloud causing the seen outcome we're all common with.
