3. You
might
have
seen
voltage
fluctuaAons
at
your
home,
which
may
cause
damage
to
any
working
electrical
appliance.
What
one
needs
is
a
protecAon
device
or
circuit,
which
can
be
installed
to
curb
out
the
voltage
spikes
and
provide
a
constant
voltage
output
to
electrical
devices.
For
this,
we
can
use
a
zener
diode
as
a
voltage
regulator.
In
this
project,
you
will
connect
two
loads
(resistors)
in
series
and
connect
their
combinaAon
to
a
fluctuaAng
voltage
source
(using
a
preset)
and
test
the
Kirchhoff’s
law.
However,
when
you
connect
a
zener
diode
in
parallel
to
one
of
the
loads,
the
voltage
across
the
corresponding
load
becomes
constant
aPer
the
reverse
breakdown
voltage
of
the
zener
diode
is
achieved.
All
the
voltage
readings
are
taken
using
a
mulAmeter
and
Kirchhoff’s
Voltage
law
is
verified
in
the
circuit
under
different
input
voltages.
