verkkojännitettä

Verkkojännite refers to the standard voltage supplied by the electrical grid in a particular region. It is the alternating current (AC) voltage that powers homes and businesses. The specific value of verkkojännite varies by country and sometimes by region within a country. For example, in many European countries, the standard verkkojännite is 230 volts, while in North America, it is typically 120 volts. This voltage is delivered through a network of power lines and substations.

The frequency of the alternating current is also a standard associated with the verkkojännite. In most of the world, this frequency is 50 hertz (Hz), meaning the voltage changes direction 50 times per second. In North America and some other regions, the standard frequency is 60 Hz. Electrical appliances and devices are designed to operate within a specific voltage and frequency range. Using a device designed for one standard on another could lead to malfunction or damage. Adapters and transformers are used to convert between different verkkojännite standards. The reliable supply of verkkojännite is crucial for modern society, powering everything from lighting and heating to communication and industrial machinery.
