This is the design and construction of an Automatic Phase Selector. In the construction work, LM324 integrated circuit (comparator) and 2N2222 transistors were used as active components alongside other passive components. The circuit components were mounted on a Vero board. Result shows that, when the three phase A.C inputs: Red phase (P1), yellow ... Continue Reading
