Rice cookers are favored by people because of their beauty, convenience, and power consumption. However, there are often cases where the service life is shortened due to improper maintenance. In order to use and maintain rice cookers reasonably to extend their service life, the following p
With the gradual development of the domestic automotive industry, the cake in the LED automotive lighting market is gradually optimistic. Then, is the LED automotive lighting market a smooth one? Where is the future demand for the automotive lighting market? What are the risks in entering the LED au
In the study of new and old batteries, suppose the new battery's electromotive force is E, the internal resistance is r, the old battery's electromotive force is Ec, the internal resistance is rc, and the load resistance is R. When two new batteries are connected in series, the road end
