Question

Может ли считаться электрическим током: 1. электрическая искра между плюсами электрической машины; 2. атмосферный электрический разряд; 3. падение заряженных капель?

Answer 1

1 Да, перемещение заряда идет
2. да, аналогично
3 тоже 

Answer 2

Can the following be considered electric current?

1. Electric spark between the positive terminals of an electric machine. 2. Atmospheric electric discharge. 3. Falling charged droplets.

Electric current refers to the flow of electric charge in a conductor. Let's examine each scenario to determine if it can be considered electric current.

1. Electric spark between the positive terminals of an electric machine: An electric spark is a brief discharge of electricity that occurs when there is a potential difference between two conductors. It is a localized phenomenon and does involve the flow of electric charge. Therefore, an electric spark can be considered a form of electric current.

2. Atmospheric electric discharge: Atmospheric electric discharge refers to phenomena such as lightning, which occur due to the movement of electric charges in the atmosphere. Lightning is a natural form of electric current that occurs when there is a difference in electric potential between the ground and the atmosphere. Therefore, atmospheric electric discharge can be considered a form of electric current.

3. Falling charged droplets: When charged droplets fall, they can create an electric current due to the movement of electric charges. This phenomenon is known as precipitation electrification. However, it is important to note that the electric current generated by falling charged droplets is typically very weak and localized. Therefore, while it involves the movement of electric charges, it may not be considered a significant form of electric current in most cases.

In summary, both an electric spark between the positive terminals of an electric machine and atmospheric electric discharge can be considered forms of electric current. Falling charged droplets can generate a weak electric current, but it may not be significant in most cases.
