ABSTRACT
Alternating Current (AC) is used in large areas and in all different life facilities, for ease of generating. AC generators are electrical machines that operate on the principle of electromagnetic induction to generate electric power. The advantages of alternating current are as follows: changes in value and direction and the polarity are not fixed; generates mechanical methods by cutting magnetic fields such as generators; and low cost of production, especially when generated with large power. The alternating current changes in value and direction on a sine. It is the highest value of the current direction, and arises in the case where the direction of the movement of the terminals of the coil is vertical on the lines of the magnetic field. In a parallel R-C circuit, the voltage of the circuit is the same at terminals of both resistance and capacitance.
