Why when voltage applied to only one phase of the primary side voltage is produced in all the three phases of secondary in a transformer?
Your question doesn't describe under what circumstances the transformer is being used.
Normally, a two wire (hot and ground) AC voltage can only be a single phase supply. Look up the explanation of how AC current cycles on a sinewave (60Hz is 60 sinewave cycles per second). This is also known as a single phase.
Coming into a standard residential house is a three wire line with two hot wires and a ground wire. The two hot wires are out of phase with each other (opposite sinewave).
A standard transformer can have multiple outputs with various/same voltage. Look up how a transformer works. Without special electronic components for each output circuit, all taps will be in phase. A transformer outfitted with the special electronic components is very expensive and not for normal everyday use.

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 do you calculate current flow transformer when 240 Vrms is supply?
The secondary current of a transformer is determined by the load and the secondary voltage applied to that load, and this, in turn, will determine the primary current by the inverse of the turns ratio. However, if you are asking about a transformer's rated secondary and primary currents, then you need to divide the transformer's apparent power rating (expressed in volt amperes) by the rated secondary and primary voltages respectively.
What are the two coils in a transformer?
primary and secondary coilsAnswerPrimary and secondary windings.
HOW do I SELECT A STEP DOWN TRANSFORMER?
By looking to the number of turns in the Primary and Secondary Coils. "A Step down transformers are designed to reduce electrical voltage. Their primary voltage is greater than their secondary voltage. This kind of transformer "steps down" the voltage applied to it."
When 440 volts and 300 amps is given as an input to the transformer the output obtained is 11 kva in this secondary current will decrease or not?
Your question reveals a misunderstanding of how a transformer works.The primary current of a transformer is determined by the secondary current, not the other way around. When the secondary voltage is applied to a load, a secondary current flows, and its value is determined by the secondary voltage and the load impedance. This secondary current then determines the value of the primary current.
Given a Transformer with 110vac at 1 amp applied to the primary with 1000 turns and the secondary of 500 turns what is the voltage current and power of the secondary?

If DC is applied to the primary of a transformer is there any current in the secondary and if there is then whether ac or DC?
first, understand that a transformer is an AC DEVICE. it wont work on dc...

How can you find primary from secondary coil?
Primary and secondary are only terms of convenience based on the ratings and purpose of the transformer. If a transformer is labeled 120 to 240 volts, just pick a winding and apply 120 VAC. If the output is 240 volts you found the primary and secondary. If you apply 120 volts and get 60 volts out that means the side where you applied 120 VAC is the secondary.
What will happen if you give DC input to the primary of a transformers?
If DC voltage is applied to the primary of a transformer the flux produced in the transformer core will not vary but remain constant in magnitude therefore no emf will be induced in the secondary winding except at the time of switching on.Also there will be no self induced emf in the primary winding to oppose the applied voltage and since the resistance of the primary winding is quite low heavy current will flow through it which may result in burning out of primary winding.
How voltage is measured in potential transformer?
By connecting a voltmeter across the secondary terminals of the voltage/potential transformer. The transformer acts to reduce the voltage applied to its primary winding, while electrically-isolating the primary (usually high-voltage) circuit from the voltmeter.
What happen if the number of loops in the primary and secondary coils in a transformer are the same?
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.
What is the different of induction transformer and automatic transformer?
Neither of these terms is normally applied to a transformer. You may be thinking of a 'mutual tranformer' and an 'autotransformer'. If so, then a 'mutual transformer' is a transformer which has electrically-isolated primary and secondary windings, whereas an 'autotranformer' (the term, 'auto', is misleading and has nothing to do with the transformer being 'automatic'!) has a common and series winding, meaning that the primary and secondary sides are electrically connected to each other.
