sekundärspole

The term "sekundärspole" is a German word that translates to "secondary coil" in English. It refers to the coil of wire in an electrical transformer that receives its magnetic flux from the primary coil. Transformers are devices that transfer electrical energy from one circuit to another through electromagnetic induction.

A transformer typically consists of two or more coils of wire, known as windings, that are electrically insulated from each other but are often wound around a common ferromagnetic core. The primary coil is connected to the input voltage source, and the secondary coil is connected to the load where the transformed voltage is required. When an alternating current flows through the primary coil, it generates a changing magnetic field. This changing magnetic field then induces a voltage in the secondary coil.

The ratio of the number of turns in the secondary coil to the number of turns in the primary coil determines whether the transformer is a step-up transformer (increasing voltage) or a step-down transformer (decreasing voltage). The voltage induced in the secondary coil is proportional to the rate of change of the magnetic flux and the number of turns in the secondary coil. The secondary coil is essential for the operation of transformers, enabling the efficient transmission and utilization of electrical power at various voltage levels.
