ensiöjännitteen

Ensiöjännite refers to the primary voltage in a transformer. A transformer is an electrical device that transfers energy between two or more circuits through electromagnetic induction. It is typically used to increase or decrease alternating current (AC) voltages. The primary winding is the coil of wire that is connected to the input power source. When an AC voltage is applied to the primary winding, it creates a changing magnetic field in the transformer's core. This changing magnetic field then induces a voltage in the secondary winding, which is the coil of wire connected to the output circuit. The ratio of the voltage in the primary winding to the voltage in the secondary winding is determined by the ratio of the number of turns in each winding. If the primary winding has more turns than the secondary winding, the transformer is a step-down transformer, reducing the voltage. If the secondary winding has more turns than the primary winding, it is a step-up transformer, increasing the voltage. The concept of ensiöjännite is fundamental to understanding how transformers operate and their applications in power distribution, electronics, and various industrial processes.
