What is voltage used for?
You surely remember those science classes in which you learned voltage used how electric circuits work. Basically! it’s a way of realizing the importance of energy in our lives . Without it! we couldn’t do most of our activities. But now! do you know what voltage is? Could you measure it? Do you know the types that exist?
Over time! we forget many things from school. This is normal unless you’re a professional in this sector. However! there are some concepts that can be very useful in everyday situations. Voltage is one of them and that’s why we’re going to review the highlights.
Don’t worry! in this case! there won’t be a final exam. We just want to buy country b2b & b2c email address list explain in detail what electric voltage is! how you can measure it if you need to! and what it’s used for.
What is voltage?
To understand what voltage is! we must remember that electricity is the flow of free electrons between atoms. Electric current cannot exist without this movement! which! in turn! only occurs when there is a potential difference in the path along which the electrons circulate.

It is true that without voltage! electrons can move just the same! but they do many film franchises so freely! at random. Only when we apply this tension or voltage! the electrons move in the same direction between two points and generate the current we need.
In our daily lives we are not aware that we are surrounded by voltages! but one question is enough to understand everything: how many sockets do you have at home?
If you look closely! the sockets
Two holes and there is a difference of 230 V between them (this is how volts are symbolised! the unit that measures voltage). This is normal in domestic electrical installations! although years ago they were 220 V.
Well! when you plug in your laptop charger! electrons start to circulate between these two points and an electric current with a voltage of 230 V is generated that fills your computer with energy aob directory so that you can then take it with you and use it anywhere.
Knowing what voltage is allows you to better understand how everything that needs electrical power works.
Did you know that voltage can vary depending on the country?
If you are going to travel! we recommend that you check the voltage of the plugs at your destination in advance to avoid breakdowns in electrical appliances.
