Starting winding has more resistance and less induction than main winding, this means has smaller diameter and less turns.
I think the resistance value of starting winding is less than the running winding of the single phase motor
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.
An 'armature winding' is the rotor winding, and the 'field winding' is the stator winding.
The higher-voltage winding has more turns (therefore its conductor will be longer) than the lower-voltage winding and, because it will carry less current, its conductors will have a lower cross-sectional area. Consequently, the higher-voltage winding will have a higher resistance than the lower-voltage winding.
Back emf is proportional to the flux in the field winding.Flux in the field winding is proportional to the mmf in the winding.mmf = current passing through the winding * no of turns in the windingTo attain the required mmf we can use more current and less turns ( or ) less current and more turns .As the power loss in the field winding is considered it isPower loss = Square of voltage / resistanceAs the voltage is constant for a high resistance it is possible to have less losses. So we prefer for high shunt field resistance.As the field resistance is high current is less , so no of turns in the shunt field will be more to attain the required mmf.Answer'Shunt' is an archaic term for 'parallel', so the shunt winding is in parallel with the supply voltage which means its resistance must be relatively high to limit the current passing through it.Incidentally, the back-emf. is not proportional to the flux, but to the rate of change of flux.

The series winding takes the full load current of the generator. So it require only a few turns to produce the required magnetic field and so the resistance is lower.

Injecting power into the higher voltage winding of a transformer will make it act as a step down transformer; injecting power into the lower voltage winding will make it act as a step up transformer. A transformer can be used both ways.
Since you got an injury before, now you know what to avoid when running. The injuries usually come from the quick turns that you take. Try to make less or easier turns.
If it's a step up or step down transformer and you know the secondary side current, multiply the secondary current by the turns ratio. If you know the power in the secondary winding but not the current, divide the secondary power by the secondary voltage to get the secondary current and then multiply the secondary current by the turns ratio to get the primary current. The turns ratio is the number of turns on the secondary winding divided by the number of turns on the primary winding. For a step up transformer, the turns ratio will be greater then one. If it's a step down transformer, then the turns ratio will be less than one. If you don't know the turns ratio, divide the secondary voltage by the primary voltage to get the turns ratio.
If power were greater at secondary you would have an unlimited source of power. It is less because there are always losses in a transformer.

1500A. You probably have pri / secondary confused. primary is usually used to denote the higher voltage winding, which will have more turns than the secondary. The secondary will have lower voltage, less turns, but will carry more current.
