The trick is to look for a sticker on the power adapter or plug that tells you the input voltage. The magic words to look for are something like this: “100-240V AC 50/60Hz”. 100-240 tells you the voltage range: Europe standardized on 220 volts for its standard household power supply .
Read moreIs Europe still 50Hz?
European countries use 50Hz They decided to use 50Hz instead of 60Hz, because they use a decimal (US using duodecimal), this calculation is more convenient, but they still retained the voltage of 110V. Unfortunately, 50Hz AC efficiency is far poorer than 60Hz.
Read moreWhat is the advantage of increasing frequency?
Higher frequencies provide more bandwidth ; you could send far more data in less time with a VHF antenna than a lower frequency antenna.
Read moreWhy is frequency so important?
Maintaining a consistent electrical frequency is important because multiple frequencies cannot operate alongside each other without damaging equipment . This has serious implications when providing electricity at a national scale.23 Haz 2017
Read moreWhy is frequency control important?
Frequency control is critical to the operation of the power grid . On the grid generation must equal load to maintain a constant frequency. If frequency goes out of bounds then there is either too much or too little generation available.
