100
its the electric force per unit charge
What is Electric Fields
100
the flow of electric charge periodically reverses direction
What is Alternating Current
100
several related concepts or gravitational and inertial mass
What is Equivalent Resistance
200
are produced by electric currents
What is Magnetic fields
200
A magnet mainly of coil of insulated wire wrapped around a soft iron core that is magnetized only when current flows through the wire.
What is elctromagnet
200
its the electric potential energy per unit charge
What is voltage
300
a area within a magnetic material which has uniform magnetization
What is Magnetic Domain
300
production of a electromotive force across a conductor when exposed to magnetic fields.
What is Electromagnetic induction
300
the ratio of the voltage applied to the electric current which flows through it
What is resistance
400
Either two limited areas in a magnet at which the field of the magnet is the most intense
What is Magnetic Poles
400
Step up -fewer turns on a coil thats carries the source of the power that are on a second coil will provide same power but higher votlage Step Down- fewer turns on the second coil outgoing power will have a lower voltage
What is transformers Step up and Step down
400
the rate at which charge flows through a surface
What is current
500
May flow in a conductor like a wire, but can also flow through semiconductors, insulators, or even vacuum as electron or ion beams
What is Direct Current
500
the moving part of a rotary electrical switch in certain types of electric motors or electrical generators
What is Communtator
