If the number of turns in the primary is the same as the secondary, this would be an isolation transformer. Primary and secondary voltages should match (minus the inherent transformer losses), as should the current.

How many turns in secondary coil in Transformer?
It depends on the type of transformer.If it is a step up transformer the number of turns in secondary side is higher than primary.Stepdown means it will have fewer number of windings on the secondary side turns when compared with the primary side.An isolation transformer has the same number of windings on the primary as the secondary.The ratio of the windings is proportional to the increase or decrease in the secondary voltage. For example, twice the windings doubles the voltage and 1/2 the windings halves the secondary voltage. The isolation transformer is denoted as 1:1 and has the same voltage on the secondary as the primary.The ratio of secondary turns to primary turns is the same as the ratio of secondary voltage to primary voltage.e.g. if the secondary to primary turns ratio is 1/10, then the secondary voltage will be one tenth of the primary voltage.
Why is the number of turns in primary coil more than that of the secondary coil?
The number of turns or windings of a transformer can vary. There can be more in the primary, or more in the secondary, or there can be an equal number in a transformer that is simply used for isolation (an isoformer). More turns in the primary than secondary will create a step down transformer. More turns in the secondary are found in a step up transformer. The transformers on power poles have more turns in the primary to step the line voltage down for delivery to residential customers.
How can you identify which one is step up or step down transformer?
A transformer has two windings, termed the 'primary winding' and the 'secondary winding'. The primary winding is the winding connected to the supply, while the secondary winding is connected to the load. The secondary voltage of a 'step up' transformer is higher than the primary voltage; the secondary voltage of a 'step down' transformer is lower than the primary voltage. The simplest way to determine whether a transformer is a step up or step down, is to measure the primary and secondary voltages. If you are simply looking at a transformer, then the transformer's insulated bushings will give you a clue -the higher voltage bushings are much bigger than the lower voltage bushings. If you have access to the inside of the transformer, then the higher voltage windings are thinner and have a greater number of turns than the lower-voltage winding.
What is high voltage side?
You are probably describing a transformer. The 'high voltage side' of a transformer is the winding with the greatest number of terms. It could be the primary or the secondary winding.
Are number of turns on primary side and secondary side same in case of star star connections?
The number of primary and secondary turns, or turns ratio, determine the secondary voltage given a particular primary voltage. So, for instance, if the primary voltage is 480/277 wye, and the desired secondary voltage is 208/120 wye, the turns ratio would be 2.3:1. If the primary and secondary voltages are the same, then yes, the number of turns on primary and secondary would be the same. But if you're not converting delta to wye or vice-versa, why would you have a transformer with the same input and output voltage, other than an isolation transformer?

Difference between input and output transformer?
The 'input' side of a transformer is called its 'primary' side, whereas the 'output' side is termed its 'secondary' side. The ratio of its secondary to primary voltage is equal to the ratio of the number of turns in the secondary windings to the number of turns in the primary winding. So if, for example, a transformer's secondary winding has twice as many turns as its primary winding, then the secondary winding will produce twice the voltage applied to the primary winding.

How does a step down transformer work?
well the working of the step doen transformer depends on the number of turns on the secondary side of the transformer, now in the case of a step down transformer, the number of turns in the secondary windings are less as compared to the number of turns at the primary side/winding, so the amount of flux which links the secondary side of the transformer is also less resulting in the production of less amount of emf at the secondary side. hence the status of the voltage is decreased as compared to the voltage of the primary side.
How does a step-down transformer work?
well the working of the step doen transformer depends on the number of turns on the secondary side of the transformer, now in the case of a step down transformer, the number of turns in the secondary windings are less as compared to the number of turns at the primary side/winding, so the amount of flux which links the secondary side of the transformer is also less resulting in the production of less amount of emf at the secondary side. hence the status of the voltage is decreased as compared to the voltage of the primary side.
What determines the transformer ratio?
Transformer ratio, more correctly turns ratio, is the number of turns in the primary winding divided by the number of turns in the secondary winding.
How much is the secondry voltage vs with a primary voltage is vp equals 120v?
As far as a transformer is concerned, the secondary voltage Vs value cannot be determined by the primary voltage Vp alone. For the simplest of calculations the transformer primary-secondary turn ratio must be known. For an ideal transformer ( and practicaly ideal transformers don't exist as there will be various losses in the transformer cores and windings), the simple equation relating secondary voltage to primary voltage would be : Vs/Vp=Ns/Np=Ip/Is where Ns is the number of winding turns in the secondary of the transformer, and Np the primary. Ip is the primary current and Is the secondary.
How the secondary voltage in transformer is stepped up?
The secondary voltage in a transformer is stepped up by having more turns in the secondary coil compared to the primary coil. This creates a higher electromagnetic induction which leads to a higher output voltage. The ratio of the number of turns in the primary coil to the number of turns in the secondary coil determines the degree of voltage stepping up.

What is the definition of transformation ratio?
The turns ratio of a transformer is the number of primary turns to secondary turns. This defines how the transformer will change the voltage and current. For N1 primary turns, and N2 secondary turns, N1/N2 will be the turns ratio; the secondary voltage will be:the primary voltage x (N2/N1); The secondary current will be:primary current x (N1/N2)
Is the transformation ratio constant for a given transformer?
Yes, since it depends on the number of turns on primary & secondary winding.
What is high voltage side?
You are probably describing a transformer. The 'high voltage side' of a transformer is the winding with the greatest number of terms. It could be the primary or the secondary winding.
