A Transformer receives a sinusoidal input signal and converts it to an output signal. During this conversion process, there are no physical connections between this two. This conversion actually happens by the two or more insulated copper wire coils (which are denoted as windings) wrapped around a magnetic iron core. Audio Transformer uses this isolation property and creates isolation between the output speakers or audio circuitry with the transformer’s input side amplifier system. In such...

The operating principle of an audio transformer is based on the principle of electromagnetic induction. It consists of two or more coils of wire wound around a common magnetic core. When an alternating current (AC) flows through the primary coil, it creates a magnetic field around the coil. This magnetic field then induces a voltage in the secondary coil, which is proportional to the number of turns in the secondary coil compared to the primary coil. The primary coil is connected to the input...
