Title: Mathematically analysis to improve efficiency of simple AC generator in term of special relativity
Abstract: The generator is one of the tools that used in power system circuit. The working system of electrical generators is converted the mechanical energy from an external source into electrical energy as output. The generator works by exploiting the electric flux generated by a magnetic field that passes through the rotation of the coil on the generator engine. Both of these are things that affect the efficiency level of the generator. If the efficiency of a generator is higher so the electrical energy generated is also greater. In this paper will be analyzed theoretically mathematically to improve the efficiency of the alternating current generator. The analytical review will be performed on magnetic field strength and coil rotation speed. With the increase of these two factors is expected to increase generator efficiency is also increasing so that the electrical energy which is the output of the generator system is also higher.
