back to the basics
referred to as the founder of modern physics
James Clerk Maxwell p 370
on an electrical charge, these lines go out from a positive charge and go into a negative charge
field lines p376
current that flows from the positive side of the battery to the negative side; this is the way the current is drawn in circuit diagrams, even though it is wrong
conventional current p 386
a cluster of many atoms whose magnetic fields align and so act like a magnet
magnetic domain p393
on a battery, this indicates how hard the battery pushes electrons through an electrical circuit
voltage p383
this scientist invented the electric generator and electric transformer
Michael Faraday p 370
charging an object by rubbing two items together so that electrons transfer from one item to the other
these are materials in which electrons can easily flow
electrical conductors p386
the force a magnet exerts on another magnet, on metals, or on moving charges
magnetic force p395
unit of measure for electrical current
amperes p383
these charges repel one another
like charges p 372
charging an object by allowing it to come into contact with an object that already has an electrical charge
charging by conduction
these are materials in which electrons cannot easily flow
electrical insulators p386
this scientist discovered that electrical forces obey a law similar to Newton's law of universal gravitation, they are referred to as the principles of electromagnetic force
Charles-Augustin de Coulomb p375
these two things work together on an electrical circuit to tell you how much an electrical circuit can do, and only one of these needs to be large for the electrical circuit to become dangerous
voltage and amps p383-384
these charges attract one another
opposite charges p373
charging an object without direct contact between the object and a charge
charging by induction p381
a materials ability to oppose the flow of electric current
resistance p 387
t/f all electrical charges repel or attract one another
true p374
t/f the resistance of a wide piece of metal is lower than a narrow piece of the same metal
true p389
the area around a charged particle that affects the other charges that enter the space
electrical field p376
the rate of flow of electrons moving past a fixed point in an electrical circuit
electrical current p 383
a circuit that does not have a complete connection between the two sides of the power source; as a result, current does not flow by
open circuit p 390
t/f if you double the electrical charge, you double the electrical force
true p374
light bulbs in this type of circuit won't work if one of them burns out
series circuit p391
