A transformer is an electrical device that is used to change the voltage level of an alternating current (AC). It operates on the principle of electromagnetic induction and requires a varying current (AC) to induce a voltage in its coils. Transformers are not designed to work with direct current (DC) because DC does not create a changing magnetic field necessary for the induction process.
Therefore, a transformer can transform AC voltage, but not DC voltage.
∴ The correct answer is option 2.
