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.


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.


When can be current in a primary coil induce a current in a secondary coil?

Secondary current = Primary current *(Number of secondary turns /Number of primary) turnsAnswerA current isn't 'induced' into the secondary winding of a transformer. It's a voltage that is induced into the secondary winding.Provided the secondary winding is connected to a load, the secondary voltage then supplies a secondary current which is determined from (Is = Vs/Rload). The primary current then depends upon the value of the secondary current and the turns ratio.


A transformer with a primary of 1200 turns and a secondary of 400 turns has what ratio?

A transformer primary of 1200 turns with a secondary of 400 turns is a ratio of 3 to 1.


An isolation transformer has 500 turns on the primary winding how many turns are on the secondary?

An isolation transformer is intended to isolate the ground path in the primary from the secondary while maintaining the same voltage on the secondary. This means a turns ratio of 1 to 1. If there are 500 turns on the primary, then there will be 500 turns on the secondary.

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.


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 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)


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!


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.


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 do you calculate primary current?

If it's a step up or step down transformer and you know the secondary side current, multiply the secondary current by the turns ratio. If you know the power in the secondary winding but not the current, divide the secondary power by the secondary voltage to get the secondary current and then multiply the secondary current by the turns ratio to get the primary current. The turns ratio is the number of turns on the secondary winding divided by the number of turns on the primary winding. For a step up transformer, the turns ratio will be greater then one. If it's a step down transformer, then the turns ratio will be less than one. If you don't know the turns ratio, divide the secondary voltage by the primary voltage to get the turns ratio.
