How would you wind a coil which has a resistance but essentially no inductance?

I wouldn't. I doubt this is possible. Wire, by definition will have inductance. The inductance will increase as the frequency increases, so I guess you could specify a frequency that is extremely low to use the coil at.

Why is there a difference in current in a coil when you apply dc voltage and then AC voltage to it?
A coil has both resistance and inductance. When you apply a d.c. voltage, the opposition to current is the resistance of the coil. When you apply an a.c. voltage, the opposition to current is impedance -the vector-sum of the coil's resistance and its inductive reactance. Inductive reactance is proportional to the inductance of the coil and the frequency of the supply.

Inductance
What is the total amount of inductance measured in millihenries?
The inductance of a coil is not related in any simple way to the length of the wire or other conductor of which it is wound. The inductance is at least as heavily influenced by the diameter of the coil.
Why in coil power factor is low?
A coil of wire acts as an inductor; it will have a very small resistance, and a relatively large inductance. Power factor is effectively the resistance divided by the impedance (made up of resistance and inductance), so the larger the inductance relative to the resistance, the lower the power factor will be.
What are the parameters of choke coil?

The Q factor of a radio coil is?
if its an LCR circuit then Q=wL/R where W=angular frequency L=Inductance of the coil R=resistance of the coil
What is ideal choke coil?
An ideal choke coil has only inductance. It has zero resistance and no stray capacitance, therefore no resonances.
What is pressure coil capacitance?
The series resistance (swamping resistance and multiplier) in pressure coil circuit has many turns.So in addition to inductance seen before, there are inter-turn capacitance also.If this capacitance effect exceeds the inductance effect, a phase-shift in pressure coil current will cause an error.When pressure coil capacitance roughly equals the inductance, the errors cancel each other.In most cases the inductance is more than the capacitance and thus the shunting capacitor mentioned before will serve the purpose.
