Answer:
Interference
Explanation:
Interference is a phenomenon that occurs when two waves meet while traveling along the same medium.
Answer:

Explanation:
As the current density is given as

now we have current inside wire given as




Now by Ampere's law we will have



We know that the electric field is equal to 1 E 6 V/m
The distance between the thundercloud and the ground is 1.6km = 1600m
Electric field = Voltage/distance
This means that the breakdown voltage must be equal to
V = 1 E 6 V/m * 1600m = 1.6 E 9 V = 1.6 GV
