The voltage x current (power) is the same on the primary coil of a transformer to the secondary coil of the transformer.
For example if you were told that the primary voltage (Vp) and current (Ip) into a transformer was 10volts and 5amps and the secondary voltage (Vs)was 25 volts you could work out the secondary current (Ip) is 2 ( 10x5/25=2)
