William Gilbert

A court physician; he published a book wherein he classified substances as “electrics” and “nonelectrics”

Insulator

According to William Gilbert this is what he meant by “electrics”

Conductor

According to William Gilbert this is what he meant by “nonelectrics”

Dielectrics

Another name for insulators

Silver

One of the best conductors among all metals

Metallic conductors

These conductors have a fixed positively charged nuclei and free roaming electrons

Liquid conductors

These conductors have free roaming positive and negative particles

Charging by induction

The method of charging or electrifying a body without any contact is called?

Electroscope

An instrument which is very sensitive in detecting the presence of a charge on a body.

Charles Agustine de Coulomb

The proponent of the Coulomb’s law for electrostatic

Coulomb’s Law

“The force between two small charged bodies acts along the line joining them and is directly proportional to the product of the two charges and inversely proportional to the square of the distance between them.”

Directly proportional

The force between the charges is __ to the product of the two charges according to the Coulomb’s law

Inversely proportional

The force between the charges is __ to the square of the distance between the charges according to the Coulomb’s law

9\*10^9 Nm^2/C^2

the constant, k, is equivalent to?

coulomb

The amount of charge that moves past a point in one second when the current is one ampere.

Gauss’ Law

It is the law that describes what an electric field will look like due to a known distribution of electric charge.

Electric field

a property of space brought about by the presence of a charge or of charges in the neighborhood

Intensity of electric field

It is the force per unit of positive test charge placed at a point.

Electric Potential

The amount of work done by an external agent to bring a unit of positive charge from a point of zero potential to the body.

Voltage

Another term for electric potential

Potential difference

It is the work done in carrying a unit positive charge from point of lower potential to the point of higher potential
