Fill in the word that completes each statement. Building up electric charges on a Van de Graaff generator is an example of static BLANK. Lightning is an example of static BLANK

Blank 1. electricity

Blank 2. discharge

Explanation:

The Van de Graaff generator is an electrostatic generator that is based on the principle of electrostatics. The process of the generator is an example of a static charge.

It consists of a belt that is made of insulating material. It is responsible for the accumulation of charges due to its continuous movement inside a hollow metal sphere. So, the number of charges gets to build upon the object.

Hence, building up electric charges on a Van de Graaff generator is an example of static electricity. Lightning is an example of static discharge.

Answer: The correct answers are electricity and discharge.

Explanation:

Van de Graaff generator is an electrostatic generator. It is used for producing high voltage static electricity. It consists of a hollow metal sphere. The charges is accumulated on it from continuous motion of the belt which is made of an insulating material.

Due to polarization, the charges builds up on an object. Van de Graaf generator is an example of static charge.

Static discharge occurs when the built-up charges flow from the object. Lightning is an example of static discharge. Lightning occurs when the clouds having an opposite charges collide each other.

Therefore, building up electric charges on a Van de Graaff generator is an example of static electricity. Lightening is an example of static discharge.
