Because it is made of pure wire with nothing beyond its length and interaction with its neighboring wires to create resistance

Why dc shunt generator does not have armature resistance?

It does have armature resistance.

What is ammature resistance?

Right now a DC engine is begun the armature is stationary and there is no counter EMF being produced. The main part to cutoff beginning current is the armature resistance, which, in most DC engines is a low esteem.

Why armature winding resistance is less than field winding resistance?

An 'armature winding' is the rotor winding, and the 'field winding' is the stator winding.

How do you measure armature resistance practically?

by using measuring meter

Why motor has large winding in shunt resistance than armature resistance?

A motor with large windings will have greater shunt resistance than armature resistance due to the sheer amount of copper wire it must travel through. The gauge of the wire also plays a part in this process.

What is ment by high resistance and low resistance on a meter?

On a multimeter, a high resistance would indicate a high Ohmic value and a low resistance would indicate a low Ohmic value. Specific values would be relative to device you are measuring.

Why the armature current of a shunt motor decreases as the motor accelerates?

Without a mechanical load the motor accelerates until the back-emf generated by the armature nearly equals the supply voltage. On load, the speed drops and the current rises until the power taken from the supply balances the mechanical power supplied to the load. If the armature has low resistance, the speed drop under load is not very much, so speed regulation is better if the armature resistance is lower.

What is the resistance value of gold?

The resistance value of gold is very low, typically around 22 microohms at room temperature. Gold is an excellent conductor of electricity due to its low resistance, which makes it useful in electronic components where low resistance is important.
