I don't understand your question. Are you asking how to convert from 60hz to 25hz using a transformer? That cannot be done. Frequency in = frequency out.
A: there is no formula the gain of the amp is just reduced by the transformer turn ratio minus efficiency or loss. the transformer is for isolation and impedance matching
If the transformer is three phase the calculation is I = 30,000 / 1.73 E. If the transformer is single phase the calculation is I = 30,000 / E. (Where I = current and E = secondary voltage) It is important to note the voltage in the first formula is line to line (typically how it is specified in three phase power systems), and the second formula it is line to neutral.
Neutral current is the vector sum of the phase currents. You should be able to add up the phase currents from their polar quantities.

Tis question is incompleet.1000 va =1 kva.This is the power capacity of transformer. A transformer having 2 currents Primary current and secondary current . for that we required both voltage. Simply we can calculate by a formula Voltage x Current x 0.8(power factor)=1000.

That's the basic purpose of all formulae - to calculate.
Electricity is not a chemical and it does not have a chemical formula. Electric current consists of moving electrons; static electricity consists of unmoving electrons.
Current is calculated on the load. If your question on transformer primary current, then use the formula N1I1=N2I2, where N1 and N2 are primary and secondary coil turns and I1 and I2 are current in respective coils. This is very basic simple formula. You have reframe your question more specifically.
Yes it does.
