Does the ratio of voltage in a primary coil to secondary coil depends on the turn of each coil?
Yes, although the question is poorly formed. The ratio of the voltage in the primary winding to the voltage in the secondary winding is the same as the ratio of the number of turns in the primary winding to the number of turns in the secondary winding. For example, if the primary had 1200 turns with the secondary having 120 turns, and the primary voltage was 50 volts, then the secondary would be 5 volts. This is a ratio of 10:1.
How do you wire star delta motor having no labels of wires?
You can't , without knowing which winding is which . 9 times out of 10 it will just trip your protection device if it's connected wrong . U need to watch for it starting i'n forward i'n star but when it kicks into delta goes i'n reverse . If u take the motor to a winding shop they should be able to identifie which winding is which .

What will happen if two generators are running in parallel but having different winding pitch?
pitch windings are used to suppressed the harmonics. while operating two gen sets in parallel having different pitch windings will certainly cause problems in reducing the harmonics . for example a generator with pitch winding 2/3 suppressed the triple harmonics but may enhance the 5th and 7th harmonics similarly a generator with pitch winding 5/6 suppressed the 5th and 7th harmonics but may enhances the triple ones . so the act would counter act each other.
In motor winding what is the difference between a lap winding and a wave winding?
When electricians and electrical engineers/repairmen are called upon to assess troubles in generators and motors, they often rewind different types of these machines. There are two families of armature (closed-circuit) windings: lap winding and wave winding, described by the commutator pitch used for winding. In mechanical terms, armature windings consist of coils connected to a commutator in Read more....direct-current machines; or coils are connected together in alternating-current machines to form groups or series.Lap winding, also called parallel or multiple winding, is the process of winding elements or coils lapping back when wound on armature cores. Lap circuits are connected in parallel between brushes. The front and back pitches are odd with opposite signs. Winding pitch equals the algebraic sum of the front and back pitches. The end of a coil is connected to the commutator and the start of the next coil under the same two poles. Single-lap windings always have the same number of current paths as field poles while double-lap windings have twice as many current paths as field poles. Triple-lap windings have three times the number of current paths as field poles.The zig-zag or wavy path of winding through slots of armatures defines single (two-circuit) wave windings and multiplex (series-parallel) windings. Half of the armature coils is connected in series and the other half is connected in parallel between brushes, no matter the number of poles. Winding pitch is equal to the sum of the front and back pitches, which both must be odd with the same sign. The end of a coil is joined to the armature and the beginning of another under the next two poles. A single-wave winding has two current paths between brush sets. The double-wave winding has four current paths between brush sets; and the triple-wave winding has six current paths.Wave winding is used mostly in small and medium sized machines (500-600 volts) for keeping the number of coils as small as possible. Applications requiring high voltages at low currents use wave windings while lap windings are used for lower voltage, higher current applications. Wave windings, for a given number of poles and armature conductors, give more emf (electric and magnetic fields) than lap windings.Examples of suitable symmetrical armature windings for DC-machines with different poles are: for two-pole machines, two-circuit lap winding is preferred over wave winding; for four-pole machines, two-circuit wave winding or four-circuit lap winding is suggested. Six-pole machines should use two-circuit wave or six-circuit lap winding since four-circuit wave winding is asymmetrical.
Is winding a past or present participle?
Winding can be a present participle when it is used as a verb form (e.g., He is winding the clock). It can also be used as an adjective, such as in "a winding road," which describes the road as having twists and turns.
What are the primary winding and secondary winding of a transformer?
The primary winding is the winding connected to the supply, while the secondary winding is the winding connected to the load. The terms, 'primary' and 'secondary' are unrelated to voltage levels.

What is a rocker arm in a DC motor and what will happen if the rocker arm connections are changed?
A rocker arm holds a carbon brush. In other words it is a carbon brush holder. Changing over the rocker arm connections is the same as changing over the armature connections and will make a DC motor turn in the reverse direction assuming that the magnetic orientation of the motor's field stays the same.More detailDC motor having a field windingIf the stator's field is created by a field winding and that winding's connections are changed over at the same time as the armature's connections are changed over, then the DC motor's direction of rotation will be the same as before.If the stator's field is created by a field winding and that winding's connections are not changed over at the same time as the the armature's connections are changed over, then the DC motor will turn in the reverse direction.DC Motor having a field created by a permanent magnetIf the stator's magnetic field is created by a permanent magnet and the orientation of that magnet is reversed at the same time that the armature connections are changed over, then the DC motor's direction of rotation will be the same as before.If the stator's magnetic field is created by a permanent magnet and the orientation of that magnet is not reversed at the same time as the armature connections are changed over, then the DC motor will turn in the reverse direction.

Why is a capacitor connected in series with starter winding?
In single phase motors, there are two windings. 1)Main winding 2) starter (auxiliary) winding. As per the double revolving theory in 1 phase machines, motor can rotate if current in the starter winding have near to 90 deg. phase shift wrt main winding. Now current flowing through capacitor leads by 90 deg. Ideally. So this is how we can get two currents which are having phase shift wrt each other. And the machine can rotate.
How long do you work for walmart before having a permanent discount card?
You should get your permanent discount card with your first paycheck if you work at Walmart.
How long should you wait to shower after having Permanent makeup done?
These are the sort of Questions you ask your Permanent Makeup Artist...its best to get information directly from them as the art of permanent makeup is constantly evolving.
what is Lap winding and wave winding?
The ends of lap windings are connected to adjacent segments of the machine's commutator, whereas wave windingsare connected between segments that are some distance apart. This results in lap windings having 2p parallel paths, where p represents the number of pole pairs; whereas a wave winding has just two parallel paths.
Are the primary and secondary of a transformer having same thickness.why?
Unless the transformer is an isolation transformer, whose primary and secondary voltages are the same, the cross-sectional area of the primary and secondary winding conductors are normally different. The higher-voltage winding has a smaller current flowing through it than the lower-voltage winding when the transformer is loaded. So the higher-voltage winding is manufactured using a conductor with a smaller cross-sectional area, therefore a smaller diameter.
Does the ratio of voltage in a primary coil to secondary coil depends on the turn of each coil?
Yes, although the question is poorly formed. The ratio of the voltage in the primary winding to the voltage in the secondary winding is the same as the ratio of the number of turns in the primary winding to the number of turns in the secondary winding. For example, if the primary had 1200 turns with the secondary having 120 turns, and the primary voltage was 50 volts, then the secondary would be 5 volts. This is a ratio of 10:1.
