A student wants

to measure

the brightness

of

different

parts

of

a

room.

She

uses

a

light

dependent

resistor

(LDR).

This

resistor

has a

high

resistance

when

it

is

in the dark.

Its

resistance

is

low when it

is in

the

light.

The

student

fits

the

LDR

in

one end

of

a

black

plastic

tube.

The
