WebNov 25, 2024 · In DC, the current flow is steady and so is the magnetic field. Since the field is steady and not changing, there is no voltage induced on the secondary and the transformer just looks like a normal coil of resistive wire to the power supply. So transformers do not work with DC currents. WebJan 27, 2024 · 1.Functions of audio transformers 1)Step up the signal voltage (increase) or step down (decrease); 2) Raise or decrease a circuit's impedance; 3) Convert from unbalanced to balanced circuits and vice versa; 4) Block DC current in a circuit when permitting the flow of AC current; 5) Separate one audio unit electrically from another.
