Voltage is the pressure that pushes electricity through wires (or other conductors) in the same way that water pressure pushes water through pipes.

What causes maximum secondary coil voltage?
I would hazard a guess and say that it is a bad coil.
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.
What is maximum output voltage of a transformer?
The secondary voltage (output voltage) of a transformer depends on the turns ratio of the transformer, and is limited by the practical insulation levels of the secondary winding, so can be very high indeed. Power transformers used in electricity transmission systems have secondary voltages in the range of hundreds of kilovolts.
Why am you losing half the voltage when rectifying secondary side of center-tapped transformer to DC via two 1n4007 diodes?
I think the answer is: if you input voltage to a grounded center-tapped secondary transformer winding, only 1/2 the voltage is applied to each rectifier at a time (sine wave), therefore the rectified voltage measured would be 1/2 that of the total voltage. The peak voltage would be 1.4 x RMS. Hope this helps.
How do you find the secondary to primary transformer voltage ratio?
Turns Ratio = (Primary turns / Secondary turns) To calculate the turns ratio you have to actually know the number of turns or wraps on the primary and secondary coils. Nobody knows that usually the manufacture of the transformer doesn't even know. So what you can use as and equivalent is to calculate the voltage ratio. So what you typically need to look for is the Input voltage and divid it by the output volatge. Usually that would be as follows; (Primary Voltage/Secondary Voltage) = Voltage Ratio
How step up transformer step up the input voltage?
It depends on the ratio of turns from primary to secondary.
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?

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.

Formula for relation between primary winding and secondary winding?
The turns ratio of Primary / Secondary tells you have the voltage and current will be changed. The secondary current will be (primary turns/secondary turns) times the primary current, and the secondary voltage will be (secondary turns / primary turns) times the primary voltage.CommentThe above answer is a little misleading, because the secondary current is determined by the load, and not by the transformer's ratio. It would, therefore, be more accurate to say that the primary current would be equal to the secondary current times the (primary turns/secondary turns) -i.e. not the other way around!
What would be the power in the secondary of a transformer that has a voltage of 48 vac and a current of 2.2 a?
48*2.2 = 105.6VA
