Tips: Which voltage in 120V and 220V is better?
Everyone knows that the power grids in many countries are different. For example, the voltage in China is 220V 50Hz; the American standard is 120V 60Hz; Japan has the voltage of 100V 50/60Hz. The different electricity grid is mainly caused by historical reasons. With unchanged power capacity, the current of 110V voltage is two times of that of 220V, the sectional area of the conductor used is also bigger, the amount of consumed copper or aluminum is also more. A higher voltage leads to a lower line loss. A lower voltage results in a higher security, but greater line loss.
