The current in the secondary when the voltage is twice the primary will be one half of the primary. The current in the primary when the voltage is twice the secondary will be twice the secondary.

How does a transformer work you mean how does it reduce current and increase the voltage you have tried the math this doesnt make any sense?
A transformer has a primary (Where the AC supply voltage is applied); and a secondary where a voltage is induced by a fluctuating magnetic field in the iron core of the transformer. The secondary voltage depends on the ratio of windings between the primary and secondary. Since the transformer can't manufacture power the product of the voltage and current at the primary exceeds that in the secondary. So if the transformer steps up the voltage in the secondary, the maximum current in the secondary must decrease. Similarly if the voltage is stepped down the maximum current increases in the secondary. There are always losses in this process so the power in is always somewhat less than power out.
Why transformer is rated inkva?
Because it's the product of the transformer's rated secondary voltage and its rated secondary current. The product of voltage and current, in a.c., is the volt ampere.Incidentally, it's 'kV.A', not 'kva'.
Difference between primary and secondary demand?
primary demand is the raw products required to make a good . secondry demand is the demand that helps the production of goods such as it for a cloth the fiber is the primary demand and secondary is financial support and so on.
Differentation between primary info and secondary info?
Primary information is information collected through research that does not already exist (surveys, questionnaires, interviews, observations, etc). Primary information is the product of primary research. Secondary information is information previously gathered and presented in finished terms (not raw data). Secondary information can come from books, scientific journals, dissertations, case studies, etc. It is the product of secondary research.
What is the rated current when a step down transformer is 50kVA and 120v in step down to 24v?
The VA of the transformer is the product of the amps x the volts. V x A = Watts. 50kVa is equal to 50,000 watts. It holds true on the primary and the secondary. The formula to use is I = W/E. Amperage = Watts (V x A)/volts.AnswerThe above answer will determine the rated currents of the primary/secondary windings. But the actual currents (which shouldn't exceed their rated values for any length of time) are determined by the load. For example, with no load, no secondary current will be flowing, and the primary current will be reduced to its magnetising current value.
When a primary color is mixed with a secondary color the new product is called what?
tertiary color
What is meaning of apparent power in transformer?
Apparent power is the product of voltage and current in an a.c. system, and is expressed in volt amperes. The rated apparent power of a transformer is the product of its rated secondary current and rated secondary voltage.
