transformaattoriin

A "transformaattoriin" is a Finnish term that can refer to a transformer, an electrical device. Transformers are used to change the voltage of alternating current (AC). They operate based on the principle of electromagnetic induction, where a changing magnetic field in one coil induces a voltage in another coil. A typical transformer consists of two coils of wire, known as the primary and secondary windings, wrapped around a common iron core. When AC is applied to the primary winding, it creates a fluctuating magnetic field in the core. This magnetic field then passes through the secondary winding, inducing an AC voltage in it. The ratio of the number of turns in the primary and secondary windings determines whether the voltage is stepped up (increased) or stepped down (decreased). Transformers are essential components in power distribution systems, allowing electricity to be transmitted efficiently at high voltages and then reduced to safer levels for household use. They are also found in various electronic devices, such as power adapters and audio equipment, for voltage conversion and impedance matching.
