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.

I have c license but I don't know eligibility of Max Kilo Volts under the electrical licensing board.
I just purchased a 4 position cam switch to be used to operate a 3-speed blower motor. The motor is a 10 amp motor and has 3 wires that are used to control speed. The cam switch was rated at 660V 20 amps but when I received it, I noticed that it has AC-15 operational current rating (Ie) of 4/5 amps. If I am reading the label correctly. the 4/5 amps is related to 440v/220V (Ue). Other ratings are AC-3: 5.5A, AC2: 7.5A and AC-4: 1.5A. My questions are 1) Is it safe to use this switch with the motor I have 2) what is the difference between the 20 amp Ith ratting and the Ie operational ratings?
