What is the relationship of primary windings of a transformer to the secondary windings regarding output and input voltage?

The phase relationship between the primary voltage and the secondary voltage of a transformer is 180 degrees (typically) on single phase Transformers.
If working with three phase transformers, a zero phase shift is often used in Y/Y grounded transformers. If the transformer is wired Delta / Wye, the phase shift will be 30 degrees. I've seen transformers with a phase shift of 150 as well (quite abnormal, but it exists!) due to the starring and a delta / wye configuration.
If you are looking at a transformer phasor diagram, this will show the phase shift between primary or secondary (three phase transformers). For single phase, there should be a drawing showing polarity markings - what goes in the polarity marking on the primary comes out on the secondary polarity marking.

∙ 11y agoThere's no physical electrical connection between the primary and secondary winding of the transformer. They are related by the magnetic field induced in the transformer core by the alternating current flowing through the primary windings.

∙ 11y ago2:1- this is a ratio If primary is 100 Seconardary would be 50 Divide both sides by the largest common number- 50 100:50 = 2:1 Refering to a winding it tells us its the number of turns of wire around a air or iron core on each side
AnswerThe winding ratio or, more correctly, 'turns ratio', of a transformer is the ratio of the number of turns in the primary and secondary winding. For an ideal transformers (most transformers are close to being 'ideal'), the turns ratio is the same as the voltage ratio. So if the secondary voltage is, say, ten times the primary voltage, then the transformer's voltage ratio is 1:10, and so, too, is its turns ratio.

∙ 7y agoThe relationship between the number of primary and secondary turns of a transformer is the same as the relationship between the primary input voltage and the secondary output voltage:
primary turns/secondary turns = primary voltage/secondary voltage

When working on a current transformer the secondary windings must be?
When working on a current transformer the secondary windings must be shorted. <<>> Properly loaded
What are the two coils in a transformer?
primary and secondary coilsAnswerPrimary and secondary windings.
What is difference betweena step up transformer and step down transformer?
The difference between the two transformers is the coil ratios between the primary and secondary windings. A transformer that increases voltage from primary to secondary has more secondary winding turns than primary winding turns and is called a step-up transformer. Conversely, a transformer with fewer secondary windings does just the opposite and is called a step-down transformer.
If a step-up transformer is to increase voltage it needs?
A step-up transformer needs more turns on the secondary windings than on the primary windings to increase the voltage.
How do you improve the flux linkage between the primary and secondary windings in a transformer?
by using an iron core
When working on a current transformer the secondary windings must be?
When working on a current transformer the secondary windings must be shorted. <<>> Properly loaded
Is it a step up or a step down a transformer has 20 primary windings and 100 secondary windings the secondary voltage is 25v?
If a transformer has 20 primary windings and 100 secondary windings, it is a step up transformer. If the secondary voltage is 25v, the primary voltage will be 5v, because the turns ratio is 20 to 100, or 1 to 5.
What is the three phase transformer?
it has three primary windings & three secondary windings.
If a transformer has 20 primary windings and 100 secondary windings and the secondary voltage is 25 what is the primary voltage?
Transformer step-up/step-down voltage is turns-ratio, so if a transformer has 20 primary windings and 100 secondary windings (a turns-ratio of 1 to 5) and the secondary voltage is 25, then is the primary voltage is 5.
What are the two coils in a transformer?
primary and secondary coilsAnswerPrimary and secondary windings.
Is 3 phase star transformer has more winding than delta?
The # of windings in a transformer are based on the primary and secondary voltages the transformer is rated for not the way the windings are connected.
What is resistance between primary and secondary winding of transformer?
The primary and secondary windings of a mutual transformer are electrically isolated, and should have 'infinite' resistance between them when measured appropriately (which depends on voltage ratings of the windings).
A transformer has 20 primary windings and 100 secondary windings If the secondary voltage is 25 V find the primary voltage?
Voltage on primary/Primary turns = Voltage on secondary/Secondary turns
What is difference betweena step up transformer and step down transformer?
The difference between the two transformers is the coil ratios between the primary and secondary windings. A transformer that increases voltage from primary to secondary has more secondary winding turns than primary winding turns and is called a step-up transformer. Conversely, a transformer with fewer secondary windings does just the opposite and is called a step-down transformer.
If a step-up transformer is to increase voltage it needs?
A step-up transformer needs more turns on the secondary windings than on the primary windings to increase the voltage.
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.
A transformer has 20 primary windings and 100 secondary windings if the voltage is 25 v what is the primary voltage?
125 v
