light dependent resistors
are dependent on light intenisty
low resistance
= bright light
high
resistance=
dark
ldr are used in
outdoor
lighting,
burgular
devices and automatic
night
lights
connect
a
bulb
in parallel to an
ldr
, the pd across both will be
high
when its dark and when dark the resistance of ldr will be
high
the
bulb
will get
brighter
as room got
darker
when connected across an ldr
