Electricity
Each device occurs one after the other sequentially
What is Simple Circuit?
He propagated the Kirchoff's Law
Who is Gustav Kirchoff?
This is a force (like gravity) and a form of energy.
What is Magnetism?
A non-permanent magnet turned on and off by controlling the current through it
What is an Electromagnet?
A device that increases or decreases the voltage of alternating current.
What is a Transformer?
Exists where components are connected across the same voltage source
What is Parallel Circuit?
The law that stated that when current is moving through a wire a magnetic field is produced
Ampere's Law
The mineral found by the Greek which exhibit attraction to iron.
What is Magnetite?
Wire wound into a tight coil, part of an electromagnet.
What is Solenoid?
This is why the compass points North.
What is the attraction of the magnetic south pole of the Earth?
In a series circuit, the sum of the voltages is _______
What is Zero?
The basic law of electromagnetism predicting how a magnetic field will interact with an electric circuit to produce an electromotive force
What is Faraday's Law of Induction?
The 3 properties that all magnets have
What is when 1) They have a north pole and a south pole 2) They exert a force 3) They are surrounded by a magnetic field
The process by which an electric current is made by changing a magnetic field
What is electromagnetic induction?
Give a way for a magnet to lose its magnetic property.
What is 1) dropping the magnet 2) putting the magnet in a strong magnetic field 3) Increasing the temperature 4) hitting the magnet all of them make the domains inside the magnet lose alignment.
In a parallel circuit, the voltage value is ______
What is Equal?
The sum of the potential drops (Resistors) equals the sum of the potential rises (Battery or cell) around a closed loop.
What is Loop Rule (Conservation Energy)?
Name 2 kinds of magnets and what they are made of.
What are Permamagnets that are made of Ferromagnetic materials (e.g. Fe, Ni, Co); and Electromagnets that are made of solenoid coils that create a magnetic field by inducing electricity.
This machine uses electromagnetic induction to change mechanical energy into electrical energy.
What is a generator?
A device that changes electrical energy into mechanical energy.
What is an electric motor?
The formula for getting the equivalent resistance of a parallel circuit?
What is 1/Req = 1/R1 + 1/R2 + 1/R3?
The sum of the magnitudes of the currents going into an intersection equals the sum of the magnitudes of the currents leaving the intersection.
What is The Junction Rule?
This always experiences a force of attraction and loses its magnetism when removed from a magnetic field
What is an Induced Magnet?
Explain the 3 steps of how an electric generator works
What is 1) A crank is turned rotating the wire coil through the magnetic field 2) This creates an electric current in one direction. 3) As the coil continues to rotate, the electric current continues in the opposite direction?
The reason why scientists think causes the Earth's magnetic field
The movement of electric charges in the Earth's core
