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

Lightning is an example of static ___

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.

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.

electromagnetic shielding is the practice of reducing the electromagnetic field in a space by blocking the field with barriers made of conductive or magnetic materials. shielding is typically applied to enclosures to isolate electrical devices from their surroundings, and to cables to isolate wires from the environment through which the cable runs. electromagnetic shielding that blocks radio frequency electromagnetic radiation is also known as rf shielding.

the shielding can reduce the coupling of radio waves, electromagnetic fields and electrostatic fields. a conductive enclosure used to block electrostatic fields is also known as a faraday cage. the amount of reduction depends very much upon the material used, its thickness, the size of the shielded volume and the frequency of the fields of interest and the size, shape and orientation of apertures in a shield to an incident electromagnetic
