This is a no load test and so it cannot be performed on series machine
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.
An equalizer, or equalizer connection, connects two or more generators operating in parallel at a point where the armature and series-field leads join (see Fig. 7.13), thusconnecting the armatures in multiple and the series coils in multiple so that the load will divide between the generators in proportion to their capacities. The arrangement of connections to a switchboard (Westinghouse Electric Corp.) is illustrated in Fig. 7.14. Consider, for example, two overcompound-wound machines operating in parallel without an equalizer. If for some reason there is a light increase in the speed of one machine, it will take more than its share of load. The increased current flowing through its series field will strengthen the magnetism, raise the voltage, and cause the machine to carry a still greater amount until it carries the entire load. When equalizers are used, the current flowing through each series coil is inversely proportional to the resistance of the series-coil circuit and is independent of the load on any machine; consequently, an increase of voltage on one machine builds up the voltage of the other at the same time, so that the first machine cannot take all the load but will continue to share it in proper proportion with the other generators
in any dc machine changing the polarity of the field will change its direction. here, in series motor, the field is in series with the armature, to which we feed the supply. hence, change the feeding polarity.
For a D.C motor it is the field windings which must always be in series with the armature windings.
A shunt dc motor has quite different characteristics from a series motor. Wired in series, the same current passes through the armature and the field winding and it is most unlikely that a shunt motor would have a field winding that is suitable for this. Therefore a shunt motor cannot be wired as a series motor in general because its field winding is designed for only a small current.

The Incredible Machine - series - happened in 360.
No, the kamehameha is a fictional energy attack from the Dragon Ball series. It cannot be performed in real life.
I find a wooden cabinet for a domestic rotary machine series 153?
I'm assuming that you mean what machine do locksmith's use, a very common machine used is the Protech series.
Connecting a machine in series with a bulb to try to use it on a higher voltage is inadvisable. The machine will have, at least in part, an inductive load, which will not equate to the purely resistive load of a bulb.
A single number cannot define a series.

It is not one machine, but a series of machines, called an assembly line.
