What is the difference between 110v and 220v?

[LaErin]

Differences are as follows: 1. Different voltages: The biggest difference between 110v and 220v is the voltage. 220V transmission consumes less electricity than 110v, and under the same wire conditions, it can effectively reduce energy loss compared to 110V. The wire cross-section for 220v transmission of the same power is reduced, saving a large amount of non-ferrous metals. 2. Transmission distance: 220V voltage has smaller losses in long-distance transmission, effectively reducing energy loss compared to 110V, resulting in lower electricity costs. 3. Wire cross-sectional area: For transmitting the same amount of electricity under the same transmission loss conditions, the wire cross-sectional area used for 220V voltage is half that of 110V, saving wire metal materials.
