Top best answers to the question «Which is better 120v or 240 volts»
Therefore: 240V system is better than 120V system. A 110VAC electric shock is a lot less dangerous than a 240V one. On the downside, an appliance with the same power rating will draw more current at 110V than at 240V , causing higher transmission losses.
There are many advantages of using 240v power compared to 120v power. When it comes down to it, the main advantage of 240-volt power over 120-volt power boils down to one simple point, and it is referred to as Joule's Law, which is : Power is equal to voltage times current.
