Half Year UV Exam Definitions Flashcards
Charge
one of the basic properties of the elementary particles of matter giving rise to all electric and magnetic forces and interactions
Electrostatic charge
Electric charge at rest on the surface of an insulated body
Electric Force Field
The region around a charged particle or object in which it exerts a force on other charged particles or objects
Electrostatic Force
The force exerted by non-moving (static) charges on each other
Basic Law of Electrical Charge
Like charges repel each other while unlike charges attract each other
Law of Conservation of Charge
The net charge of an isolated system remains constant.
Ohm’s law
Current through a conductor is directly proportional to the potential difference across the conductor at constant temperature.
Kirchhoff’s Law of Current
The sum of the current flowing into any point equals the sum of the current flowing out from the point.
Kirchhoff’s Law of Voltage
Around any closed loop in circuit, the sum of the voltage drops is equal to the EMF.
EMF
The total energy supplied per coulomb of charge by the cell.
isotope
Atoms of a specific element with the same atomic number but different mass number.
OR
Atoms of a specific element with the same number of protons, but different number of neutrons.
orbital
A region of space in which electrons with a given energy are most likely to be found.
Covalent Bond
A sharing of at least one pair of electrons by two non-metal atoms.
Intermolecular force
A weak force of attraction between discrete molecules, ions or atoms of noble gases.
Intramolecular bond
A bond occurring between atoms within molecules
