electric Field
a region around a charged particle or object within which a force would be exerted on other charged particles or objects.
electromagnet
An electromagnet is a type of magnet in which the magnetic field is produced by an electric current
motor
machine, especially one powered by electricity or internal combustion
voltage
an electromotive force or potential difference expressed in volts
induction
the act or process by which an electric or magnetic effect is produced in an electrical conductor
magnetic field
region around a magnetic material or a moving electric charge within which the force of magnetism acts.
electromagnetic induction
is a process where a conductor placed in a changing magnetic field (or a conductor moving through a stationary magnetic field) causes the production of a voltage across the conductor.
potential difference
he difference of electrical potential between two points
power
the ability to do something or act in a particular way, especially as a faculty or quality
parallel circuit
is a closed circuit in which the current divides into two or more paths before recombining to complete the circuit
magnetic domain
A magnetic domain is region in which the magnetic fields of atoms are grouped together and aligned.
transformers
A transformer is a device that changes (transforms) and alternating potential difference (voltage) from one value to another value
insulator
a substance or device that does not readily conduct electricity.
ampere
a unit of electric current equal to a flow of one coulomb per second
series circuit
is a closed circuit in which the current follows one path
direct current
an electric current flowing in one direction only.
equivalent resistance
More resistance means less current is flowing through the circuit. Equivalent resistance is a different way of indicating 'total' resistance, which we calculate differently for series and parallel circuits.
conductor
is an object or type of material that allows the flow of an electrical current
ohm
the SI unit of electrical resistance
alternating current
an electric current that reverses its direction many times a second at regular intervals, typically used in power supplies.
generator
any device for converting mechanical energy into electrical energy by electromagnetic induction, esp a large one as in a power station.
resistor
represents a given amount of resistance in a circuit
volt
the SI unit of electromotive force
