Electricity Flashcards
It is the set of phenomena associated with the presence and motion of matter that has a property of electric charge.
Electricity
The unit of charge is Coulomb which was named after
Charles- Augustin de Coulomb
It states that “the electrical force between two
charged objects is directly proportional to
the product of the quantity of charge on the
objects and inversely proportional to the
square of the separation distance between
the two objects”.
Coulomb’s law
It is a force that acts at a distance, even when objects
are not in contact with one another
Electrostatic Force
This provides a convenient graphical presentation
of the electric field in space
Electric Field Lines
Occurs when two different materials rub against each other causing the transfer of electrons. is the opposing force which acts in the opposite direction of the movement of the upper body
Friction
Occurs when a neutral object is placed in
contact with an already- charged object
Conduction
is a vector field that describes the magnetic influence of electrical currents and magnetized materials.
Magnetic Field
Occurs when a neutral object is placed in
contact with an already- charged object
Conduction
process, a charged object is brought
near but not touched to a neutral conducting
object.
Induction
No resistance to electron flow, no electric potential required and must be very cold
Superconductor
An electric conductor is a substance in which electrical charge carriers (usual electrons), move easily from atom to atom with the application of voltage
Conductor
It is a material that does not conduct an electrical current. These materials include paper, plastic, rubber, and glass.
Insulator
A solid substance that has a conductivity between that of an insulator and that of most metals. Devices made of notable silicon, are essential components of most electronic circuits.
Semiconductor
It is defined as the V = U/q. Sometimes referred to as the voltage. The greater the voltage, the greater the potential to do work.
