General Terms
A small "package" of light energy that acts like a particle
What is a photon?
the two parallel lines in a circuit diagram represent this
James Clerk Maxwell is widely known as this
What is the founder of modern physics?
the effect a charge has on other charges in the space around it
What is the charge's electric field?
Charging an object by rubbing two items together where one transfers electrons to the other
What is charging by friction?
a material's ability to impede the flow of charge
What is resistance?
this circuit allows devices to work independently of one another
What is a parallel circuit?
the inventor of the electrical generator and electrical transformer; Maxwell met him at King's College
Who is Michael Faraday?
The more charge a particle has, the more ____ it can exchange.
What are photons?
What is static electricity?
A molecule that has two poles; scientists have not found a monopole yet
What is a dipole?
The longer of the two parallel lines representing the battery represents the ____ end of the battery.
What is positive?
Maxwell was accepted into Edinburgh University at the age of ____
What is 16?
The first principle of electromagnetic force is that like charges ____ and opposite charges ____.
What is repel and attract?
materials that are made permanently magnetic
What are ferromagnetic materials?
how hard a battery "pushes" electrons through an electrical circuit
What is voltage?
the amount of charge that travels past a fixed point in an electric circuit each second
What is electrical current?
the book Maxwell wrote with 40 mathematical equations to show that electricity and magnetism were governed by the same force
The second principle of electromagnetic force is that the force between two charged objects is ____ proportional to the amount of charge on each object.
What is directly?
Charging an object by allowing it to come into contact with an object that already has an electrical charge
What is charging by conduction?
A circuit that does not have a complete connection between the two sides of the power source; as a result, current does not flow.
What is an open circuit?
Current that flows from the positive side of the battery to the negative side; this is the way current is drawn in circuit diagrams, even though it is wrong.
What is conventional current?
Maxwell's 40 equations were eventually reduced to ___ after the later experiments of Heinrich Rudolph Hertz
The third principle of electromagnetic force is that the force between two charged objects is _____ proportional to the square of the distance between them.
What is inversely?
Charging an object without direct contact between the object and a charge
What is charging by induction?
