Sorry Then here's your shmoop du jour brought to you

00:05

by resistance it's an important concept in physics and in

00:09

parents especially when you're learning how to drive like that

00:14

All right which of the following describes a method of

00:16

increasing the resisted ity of a given medal and here

00:21

the potential answers can cool down Heated up burn It

00:25

sounds like dating All right so what is resisted ity

00:29

well before we get ahead of ourselves let's start with

00:31

this matter Allows for the passage of charge after all

00:36

that's how electricity gets from the power plant to your

00:38

house It's passes through wires to get there But some

00:42

materials like rubber or plastic are highly resistant to charge

00:47

that's Why Power lines have special insulation that make sure

00:50

the electricity and stays in the wires Gold leak out

00:53

play with birds World's love that insulation here All right

00:57

so how can you make something mohr resistant to electricity

01:01

Well everything is made up of little particles right Protons

01:05

neutrons electrons which make up atoms which make up molecules

01:09

which make up bigger things like a wire or are

01:12

gorilla And even though a length of wire might look

01:16

like it's just sitting there while the particles inside of

01:18

it are vibrating Why Because that's what particles do for

01:22

a living They have to move just like us You

01:25

know when our favorite song in a solid like a

01:28

metal wire the particles air tightly packed and attracted to

01:31

each other So they're not bouncing around freely like they

01:34

do in a gas But and this is a big

01:37

but which we like and cannot lie There is still

01:40

motion going on now Electricity is basically a stream of

01:43

electrons And when that stream flows through a material it

01:47

has to get past all those vibrating particles If the

01:50

electrons bump into the vibrating particles they won't make it

01:53

all the way through and the charge will be diminished

01:56

if the material is highly resistive That means it's harder

02:00

for electricity to find its way through it So how

02:03

can you increase the resisted ity of a material while

02:06

you make its particles vibrate faster And how do you

02:09

make the particles move faster Well you heat it up

02:12

because the heat energy excites the particles Think of a

02:16

room full of preschoolers if you cool a material down

02:19

that's Like nap time for the little kids everything is

02:22

calm but adding heat is like giving the toddler's a

02:25

handful of candy filled with sugar We're gonna bounce all

02:28

over the place so are correct answers Option b heating

02:31

a material up increases resistive ity option a has it

02:35

completely backward Cooling a material reduces its resistance C doesn't

02:39

work either Reducing the quantity of something doesn't affect how

02:42

resistant it is Andy isn't really about resistive ity at

02:46

all If you destroy something by burning it it no

02:49

longer has any resistive ity and as for parents well

02:52

studying wish mum maybe one way to reduce resistance in 00:02:55.453 --> [endTime] them Oh yeah
