Voltage differs between countries due to historical reasons and infrastructure development. Different countries have established varying standard voltage levels based on their power generation and transmission systems. The differences in voltage also help ensure compatibility with appliances and electronic devices in each region.

What is the Si unit used to measure the different on voltage between two place?
Volts
Why there is different types of voltage range 210 Volt 220 Volt 230 Volt 240 Volt 250 Volt in single phase AC system and what it based?
Different voltage ranges in single-phase AC systems exist due to variations in electrical standards and utility practices across different regions and countries. The nominal voltage level (e.g., 220V, 230V) is typically chosen based on historical standards, equipment compatibility, and the balance between efficiency and safety. It's important for electrical devices to operate within their specified voltage range to ensure proper functionality and safety.
What power voltage does Europe use?
Europe's power voltage typically ranges from 220V to 240V. Different countries may have varying voltages within this range, so it is important to check the specific voltage requirement for the country you are visiting.
Can voltage increase or decrease in a system during a day?
Power supply voltages vary with the amount of load placed on them. In many countries the supply voltage has a nominal voltage and a plus or minus tolerance. In the UK the nominal voltage is 230 v but the allowable variation is -6% +10%, in other words 216-253. At my house the voltage is usually between about 236 and 253 volts.
What makes a dc bulb different from an ac bulb?
The voltage source that is applied to them is the difference between AC and DC light bulbs.
Do many countries use different mains voltage than UK?
No.
What are the benefits of traveling with a voltage converter?
if you are traveling out of the country a voltage converter is a neccessity. Because a lot of other countries use electricity on a different voltage.
What the different between voltage generators and voltage transformers?
Generators generate and transformers step up or step down the voltage
What is relation between frequency and voltage of that frequency?
voltage and frequency both are different quantity.. don't mix it...
What is the main different between the power transformer and voltage transformer?
Voltage Tarnsformer transforms only voltage. While power transformer transforms both voltage and current.
How is different between voltage and current?
voltage = the electrical "pressure"current = the electrical "movement rate" or "flow rate"
What is the frequency in different countries?
Scroll down to related links and look at "AC voltage and frequencies in the world".
What is voltage of main electricity?
It varies in different countries round the world but most use 240 volt mains.
What is the Si unit used to measure the different on voltage between two place?
Volts
What is the difference between America and the Caribbean?
different countries
The difference between short to a voltage circuit and short to a ground circuit?
A short circuit is an abnormal connection between two nodes intended to be at different voltages. A voltage circuit is caused intentionally for the purpose of voltage sensing. A ground circuit occurs between a phase and the ground.
What is different between European and Asia countries?
Um there in two different continents
