What is a coil in transformer?
In a transformer, a coil refers to a length of wire wound around a magnetic core. These coils, also called windings, are the main components responsible for transforming electrical energy from one voltage level to another. The primary coil receives an electrical input, while the secondary coil delivers the transformed output. The number of turns and the arrangement of the coils determine the voltage transformation ratio of the transformer.
Why do coils of transformers function?
Transformer coils work by creating magnetic fields when alternating current (AC) passes through them. Alternating current generates a changing magnetic flux in the coils, which induces a voltage across the windings. This process of electromagnetic induction allows the efficient transfer of electrical energy from the primary coil to the secondary coil, resulting in a voltage transformation.
Why are two coils used in transformer?
Two coils are used in a transformer to facilitate the transfer of electrical energy between the primary and secondary circuits. The primary coil, also known as the input or primary winding, receives an electrical input and generates a magnetic field. This magnetic field induces a voltage in the secondary coil, also known as the output or secondary winding, causing the voltage levels to transform. The use of two coils allows isolation between the input and output circuits and allows voltage transformation without the need for direct electrical connection.
The terms “coil” and “winding” are often used interchangeably to refer to the wire wound around the magnetic core of a transformer. Both terms describe the essential components responsible for electromagnetic induction and voltage transformation in the transformer. While “coil” generally refers to a single length of wire wound around the core, “winding” can refer to multiple turns of wire forming a single coil or the arrangement of coils in the transformer. Overall, the coil and winding play crucial roles in the operation of a transformer, facilitating the efficient transfer of electrical energy between circuits.
