What is the difference between 110v and 220v?

[HopeAnn]

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. 220v transmission of the same power reduces the cross-section of the wire, saving a large amount of non-ferrous metals. Compared to 110V, 220V can reduce the working load of the transformer, providing more safety guarantees at the power transformation node. The specific differences between 110v and 220v are as follows: 1. Loss: 220V voltage has smaller losses in long-distance transmission, effectively reducing energy loss compared to 110V, resulting in lower electricity costs. 2. Materials: For transmitting the same amount of electricity, under the same transmission loss conditions, 220V voltage uses a wire cross-section that is half the size of 110V, saving on wire metal materials. 3. Working load: Compared to 110V, 220V can reduce the working load of the transformer, providing more safety guarantees at the power transformation node.
