Statement I: If the value of the output voltage of an ideal transformer is half the value of the input voltage, then the output current will become twice. Statement II: No energy is dissipated in an ideal transformer.

Transformer is a device used to increase or decrease the voltage in the transmission line according to requirement, Generally the input line voltage is fed in a primary coil and the output line voltage is obtained from the terminals of another coil In an ideal transformer, the primary and secondary coils are linked is such a way that there is no loss of magnetic flux and electrical energy. In an ideal transformer, if the number of turns and input voltage across the terminals of the primary coils be N_1 and V_1 , then the output voltage at the two terminals of the secondary coil V_2=V_1.N_2/N_1 , where N_2 is the number of turns in the secondary coil . In the above mentioned transformer the input and output currents are respectively.
