3. Do
you
know
how
a
clock
operates?
The
hands
of
the
clock
run
in
a
clockwise
direcDon
because
the
motor
runs
in
the
same
direcDon.
Now,
if
the
direcDon
of
the
baIery
is
reversed,
the
clock
will
stop.
This
happens
because
the
diode
is
present
in
the
clock
circuit
which
prevents
the
motor
to
run
in
the
anD-­‐clockwise
direcDon.
In
this
project,
you
will
need
a
resistor,
a
diode,
a
DC
motor
and
a
few
connecDng
wires.
The
connecDons
are
made
such
that
the
resistor
is
connected
in
series
with
the
parallel
combinaDon
of
the
diode
and
the
motor.
AMer
the
compleDon
of
the
circuit,
the
motor
starts
to
rotate.
When
the
baIery
connecDons
are
reversed,
the
motor
stops
to
rotate.
The
two
phenomena
were
reasoned
doing
the
current
path
analysis
in
both
the
cases.
Thus,
the
diode
ensures
that
the
motor
does
not
rotate
in
the
opposite
direcDon
when
the
baIery
connecDons
are
reversed.
