Question 10

what are conductors usually categorised into

Answer 10

metal

Question 11

what are insulators usually categorised into

Answer 11

non-metals

Question 12

what is the one non-metal which still conducts electricity

Answer 12

graphite

Question 13

why are metals good conductors

Answer 13

because they have free electrons in them, so they are able to move

Question 14

why are insulators not good conductors

Answer 14

because they do not let electrons move easily

Question 15

which has a higher resistance, insulators or conductors

Answer 15

insulators

Question 16

what charge are electrons

Answer 16

negative

Question 17

what charge are protons

Answer 17

positive

Question 18

what charge are neutrons

Answer 18

neutral

Question 19

what is conventional current

Answer 19

a conventional current is when the current is flowing from the positive terminal, through the conductor to the negative terminal

Question 20

what are the danger of short circuits

Answer 20

they can easily cause fires, this is proved by the experiment where is is established that the electrons flow through the wire easier than the bulb. they bypass the bulb causing a short circuit, running out the battery and potentially causing fires and small explosions
