Ligthtings, refrigerators, air-conditionings, TVs, Computers, fans, etc need electrical energy which usually delivered by electrical circuit. Usually electrical wires are made of aluminium, steel and copper. We can use semi conductor but is is expensive and cumbersome to transfer a big amount of electrical energy using semi conductor. read more
