vakiojännite

Vakiojännite, also known as single-phase alternating current (AC), is a type of electrical power distribution used in many parts of the world. It is a single-phase AC system where the voltage and current change sinusoidally with time, having one positive and one negative half-cycle.

Vakiojännite is commonly used for household and commercial applications, including residential, office, and retail environments. It is well-suited for most lighting and heating applications, as well as for powering small to medium-sized appliances. The system is relatively simple and cost-effective to install and maintain.

In a vakiojännite system, the voltage is typically in the range of 110 to 240 volts, depending on the country or region. The standard frequency is 50 or 60 Hz, which refers to the number of cycles of the AC waveform per second. The system's efficiency and reliability are also notable advantages, making it a popular choice for many applications.

While vacuum tubes and some older electronic devices require three-phase power to operate, many modern electronic devices, including personal computers and televisions, can be powered by single-phase AC. Consequently, vakiojännite is widely used in the vast majority of homes and businesses, often referred to as 120/240-volt systems.

Vakiojännite's simplicity and low power loss during transmission and distribution make it a favored option for electric utilities and consumers alike. However, some industrial applications and devices, particularly those requiring three-phase power, still require a specialized connection.
