## Additional Science Flashcards

Term
 define: Open circuit
Definition
 A cicuit that does not have a complete conection between the two sides of the power source. As a result, current does not flow.
Term
 define: resistance
Definition
 The ability of a material to impede the flow of charge.
Term
 define: Conventional current
Definition
 current that fows from the positive side to the negative side, even though its wrong.
Term
 define: electical current
Definition
 THe amount of charge that travels past a fixed point in an electrical circuit each second.
Term
 define: charging by induction
Definition
 charging an objwct without direct contact between the object and a charge.
Term
 define: charging by conduction
Definition
 charging an object by allowing it to come in contact with an object that already had electrical charge.
Term
 define: photon
Definition
 A small package of light that acts like a paricale
Term
 what causes the electomagnetic force?
Definition
 the exchange of photons.
Term
 why dont charged particals glow?
Definition
 Because the photons they emit are to small for us to see.
Term
 If you were to use a positively charged rod to charge an object by induction what charge would the object have?
Definition
 negative
Term
 If you were to use a positivly charged rod to charge an object by conduction,what charge would the object have?
Definition
 positive
Term
 under what conditions is an electrical circuit reasonably safe?
Definition
 with low voltage and current
Term
 whats wrong with conventional current?
Definition
 it goes the wrong way (from the posative side to the negative side)
Term
 does a longer or shorter wire have more resistance?
Definition
 longer
Term
 [image] what type of circuit is this?
Definition
 series circuit
Term
 what type of circuit is this?[image]
Definition
 parallell circuit
Term
 is it possible to have a permanent magnet with only a north pole?
Definition
 no
Term
 Is it possable to make a magnet from something that is not a magnet?
Definition
 yes
Term
 If a material does not respond to a magnet what can you conclude about the atoms in the material?
Definition
 that the material is not megnetic and the atoms cannot be aligned.
