A transformer is a device that operates only on ac (alternating current) because it works based on the principle of electromagnetic induction. When current flows through the primary coil of the transformer, it creates an alternating magnetic field that induces a voltage in the secondary coil. This voltage is then used to power electrical devices. Therefore, transformers do not work with direct current (dc).
