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.
Does a starting winding has more or less turns than a running winding?
Starting winding has more resistance and less induction than main winding, this means has smaller diameter and less turns.
Which winding has the higher resistance start or run in single phase motors?
start winding is thicker with less number of winding whereas run winding is less thicker than start winding but with more number of winding. As we know inductance depends upon numbers of turns of winding so run winding will have more inductance.
Does a step-up transformer have a higher primary or secondary resistance?
It is a step up transformer since the secondary windings are greater than the primary. the turns ratio is (primary to secondary) 1:5, so the primary voltages is 1/5 of the secondary (5 volts).
What is resistance of stator winding of induction motor?
Resistance of stator winding is the resistance of the copper conductors being used for building the windings of three separate phases, i.e. R-Y-B. These windings are marked like U1-U2, V1-V2 & W1-W2 at the motor terminals (6 nos.) for the three phases, i.e. R-Y-B respectively. We have simply to measure the resistance of each winding by using a multimeter by connecting the terminals (2 no.) to U1 & U2 and so on. The resistance should be in ohms not milliamps [amps is form of measuring current not resistance] milliamps to microamps in case of large motors, it may be in amps in case of small sized motors. But resistance of each winding should be nearly same to each other. This shows the electrical balance among windings & also proves the healthiness of the winding.

Is the resistance in the start winding greater or less than the resistance in the run winding?
The resistance in the start winding is greater because it is longer and thinner and has the greatest resistance to current flow
Why is the shunt field resistance greater than the series field resistance?
In case of series winding total line current is flow through it.line current is very very high.so,to minimize the drop the winding made as low turns and low gauge.hence the resistance is low.in case of shunt winding high resistance winding is used otherwise short circuit the parallel winding.for that winding is made as heavy turns and heavy gauge.
How do you measure wiring winding resistance?
Through an omhmeter.
Does a step-up transformer have a higher primary or secondary resistance?
It is a step up transformer since the secondary windings are greater than the primary. the turns ratio is (primary to secondary) 1:5, so the primary voltages is 1/5 of the secondary (5 volts).
What type of test equipment would you use to check the resistance between motor winding?
Ideally megger test is the best test used to check the resistance of motor winding.

The insulation resistance of a transformer winding can be easily measured with?
It depends on the rated voltage of the transformer winding -are you talking about a 12-V transformer winding or a 400-kV transformer winding? Obviously, there is no one answer to your question!
