Conservation of energy requires that the power going in must equal the power going out.

Transformer is a device which only transforms Current to Voltage or vice versa,
so when u halve the voltage in the secondary coil, naturally the Current will be double (minus losses).

If the voltage in the secondary is twice that of the primary, the current in the secondary should be half that of the primary.
