A voltage of **110V** typically refers to an electrical potential difference of **110 volts**. It's a common household voltage in countries like the United States and Canada for small appliances and electronics.
In many parts of the world, electricity is supplied at 110V (or 120V in some regions), which is lower than the 220V-240V used in other places like Europe, Asia, and Australia.
The voltage value (like 110V) determines the electrical pressure that pushes the current through wires to power devices. The type of voltage (AC or DC) and the frequency (like 60Hz in the U.S.) can also be important depending on the device you're using.
