Countries that typically use 50 hertz and 230 volts for electricity include most European countries, as well as countries in Asia, Africa, and Oceania. Some examples include Germany, France, China, India, Australia, and South Africa.
To calculate the voltage needed for a 25 watt light bulb for 30 seconds, you would use the formula P = V * I, where P is power (25 watts) and I is current (amps). Since the time is given, we can't determine the voltage with just the power and time values. Additional information is needed, such as the resistance of the bulb, to calculate the voltage.
Electricity generation stations throughout Europe generate supplies at 50 Hz.Click on the Related Links shown below - and see the answer to the Related Question also shown below - for more information about the electricity supplies used as standard in each of the countries around the world.
Countries use either 220 volts or 110 volts based on historical decisions, grid infrastructure, and safety regulations. North America and some parts of Japan use 110 volts, while Europe, Asia, Africa, and Australia use 220 volts. Each system has its benefits and challenges, but the choice typically depends on what was established when electricity infrastructure was first developed.
220 volts is a common standard voltage for electrical systems because it allows for a balance between efficiency in power distribution and safety for electrical appliances. Additionally, the 220-volt system provides a higher power capacity compared to a 200-volt system, which is important for handling larger electrical loads.
No country in the world uses 138 volts. They use 100, 110, 115, 120, 127, 210, 220, & 240.
"50 Hz" is the shortened form of "50 hertz" which means "50 cycles per second". 50 Hz is the frequency of alternating current (ac) used by national electricity power services in many countries in Europe and elsewhere in the world whilst in USA, Canada and many other countries it is 60 Hz.
The world has not developed a machine able to make electricity from fruits.
50 Hz is the frequency of alternating current (ac) used by national electricity power services in Europe and several other world areas whilst 60 Hz is used in USA, Canada and many other countries in the world. 50 Hz means or specifies "50 cycles per second". Hz is the international technical abbreviation for the scientific unit of frequency, the hertz.

240 Volts. <><><> In USA, Canada and other countries using a similar 60 Hz houshold electricity supply system, they are dual-voltage. Some of their components, such as the timers, use 120 V while the heating element uses 240V.
British electricity is of high quality as one of the leading developed countries in the world. The most well known supplier of electricity in the UK is 'British Gas'.
