The resistance of a single (ideal) conductor is zero, its
inductance is also zero and its capacitance IS ALSO ZERO?
NO. Its capacitance is infinite. Understand it like this:
cut the conductor in two pieces and treat them as plates of
a parallel plate capacitor with air as dielectric. Now the
capacitance of this 'capacitor' is: eA/d; e is 'epsilon
zero', A is cross section of the conductor and d is distance
between the two pieces. Now bring the two pieces closer and
closer till they meet to form a single conductor. At this
point: capacitance = eA/d = eA/0 = INFINITY.
HENCE PROVED.
