on
a
capacitor
A
dc
voltage
supply
is
connected
across
the
terminals
of
a
capacitor.
The
capacitor
is
then
charged
to
that
potential
difference.
The
capacitor
is
discharged
through
a
coulomb
meter
The
amount
of
charge
stored
on
the
capacitor
is
measured
in
nano
coulombs.
You
can
change
the
charging
voltage
by
clicking
on
the
value
of
the
power
supply
on
the
dial.
Collect
values
of
voltage
across
the
capacitor
and
the
charge
stored.
