Why dc shunt generator does not have armature resistance?
It does have armature resistance.
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.
In DC motor is the armature plus brushes resistance substantially the same for every rotational position of the armature why?
In a DC motor, the armature resistance and brush contact resistance remain relatively constant across different rotational positions because these components are primarily resistive and do not change with position. The brushes continuously maintain contact with the commutator segments as the armature rotates, ensuring a consistent electrical path. While the inductance and back EMF may vary with position, the resistance itself is a fixed characteristic determined by the materials and design of the armature and brushes. Therefore, the overall resistance remains substantially the same throughout the armature's rotation.
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 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 dc shunt generator does not have armature resistance?
It does have armature resistance.
Why armature resistance is less than 1 Ohm?
why armature resistance is very low as compare to field resistance in dc motor
How do you measure the resistance of a motor?
we can measure the resistance of the motor by using voltmeter ammeter method of by directly using a multimeter across the armature terminals of the motor in voltmeter ammeter method we should use a less value of dc voltage to find the resistance

Why armature resistance is maximun in motors?
avoid high stating currents
How can you make the resistance higher in a circuit?
A: practically any series resistance will do that

If you connected the test leads of an ohmmeter to the brushes of a DC electric motor what reading would you read?
If you connect the test leads to the brushes of a DC electric motor, you would typically measure the resistance across the armature circuit. This reading can help you determine the condition of the armature winding, the brushes, and the connections.
A 100KVA DC GENERATOR HAS ARMATURE RESISTANCE 0.02 OHMS AND A SERIES FIELD RESISTANCE 0.004 OHMS WHAT IS THE ARMATURE GENETATED VOLTAGE?
There is not enough information to answer the question. A DC generator is never described in kVA because DC generators are specified in terms of kilowatts.
