vocabulary
The physical field that surrounds electrically charged particle and exerts force.
electric field
A vector field that describes the magnetic influence on moving electric charges, electric currents, and magnetic materials.
Magnetic Field
Is a region within a magnetic material in which the magnetization is in a uniform direction.
Magnetic Domain
Is the magnetic field that extends from earth's interior out into space.
Magnetic poles
Is one directional flow of electric charge.
Direct Current
Is an electric current which periodically reverses direction and changes its magnitude continuously with time.
Alternating Current
A type of magnet in which the magnetic field is produced by an electric current.
Electromagnet
Is the production of an electromotive force across an electrical conductor in a changing magnetic field
Electromagnetic induction
Is a passive component that transfers electrical energy from one electrical circuit to another circuit.
Transformers
A set of resistor in a series connection is equal to the algebraic sum of the individual resistance
Equivalent Resistance
Is a device that converts motive power into electrical power.
generator
A device that changes a form of energy into mechanical energy to produce motion.
Motor
The difference of electrical potential between two points
potential difference
Is a material in which electric current does not flow freely.
Insulator
Is an object or type of material that flow of charge in one or more directions.
Conductor
A passive two-Terminal electrical component that implements electrical resistance as a circuit element.
Resistor
Is the difference in electric potential between two points.
voltage
Is the amount of energy transferred or converted per unit time.
power
The base unit of electrical current in the international system of units.(A) symbol
Ampere
The current through a conductor between two points is directly proportional to the voltage across the two points.
ohm's Law
Electrical unit of voltage or potential difference.
Volt
Is there production of an electromotive force across an electrical conductor in a changing magnetic field.
Induction
Branches so that the current divides and only part of it flows through any branch.
parallel circuit
Comprises a path along which the whole current flows through each component.
series circuit
