Nature of Electricity Flashcards
Is a form of energy – also an energy carrier.
Electricity
It is a property of matter.
Electric Charge
True or False
The smallest units of charge exist with the electron and the proton.
True
Electrical charges are measured in the SI unit of coulomb (C). Which means 1 coulomb is equal to ________
6.25 x 10^18 electrons
It is a type of electricity that resulted of an imbalance between negative and positive charges in an object.
Static Electricity
________ of objects occurs when they gain a net positive or a net negative charge.
Electrification
It is a study of stationary or resting electric charges.
Electrostatics
It is the attractive or repulsive force between two electrically charged objects.
Electrostatic Force
It is the physical field that surrounds each electric charge and exerts force on all other charges in the field, either attracting or repelling
Electric Field
What law describes below:
The electrostatic force between two charges is directly proportional to the product of their quantities and inversely proportional to the square of the distance between them.
Coulomb’s Law
It is a type of electricity that is the steady flow of electric atom. Is more commonly known as the electric current or electricity as we know it.
Dynamic Electricity
What is the study of electric charges in motion.
Electrodynamics
What type of band is described below:
- The band contains the outermost electrons of the atom.
- Maybe partially or completely full of permitted number of electrons.
- Exist below the forbidden energy gap.
- low energy state.
Valence band
What type of band is described below:
- Populated with electrons that have become free from their original atoms.
- May be empty or partially field.
- exist above the forbidden energy gap
- High energy state
Conduction Band
A type of electrical material that readily allow a flow of electrons. Has a large number of electrons in the conduction band.
Conductors
