Principles and Practice of Engineering (PE) ExamĮlectrical engineering has many sub-disciplines, the most popular of which are high Voltage engineering (Power Companies), power engineering (Facilities), and power electronics.There are four main components of obtaining professional engineering licensure: The basis for most of the state legislation however is the National Council of Examiners for Engineering and Surveying (NCEES) Model Law. Thus, requirements for licensure can and do vary by state. In the United States, the regulation of licensed professional engineers is handled at the state level. Consulting engineers, specializing in new fields, are employed to study and recommend courses of action. The rapid proliferation of new discoveries, products, and markets in the electrical and electronics industries has made it difficult for workers in the field to maintain the range of skills required to manage their activities. Moreover, in the regulation and control of interconnected power systems, electronic computers are used to compute requirements much more rapidly and accurately than is possible by manual methods. For example, in the high-voltage transmission of electric power, large arrays of electronic devices are used to convert transmission-line current at power levels in the tens of megawatts. The distinction between the fields has become less sharp with technical progress. In this sense, electrical engineering is the branch dealing with "heavy current"-that is, electric light and power systems and apparatuses-whereas electronics engineering deals with such "light current" applications as wire and radio communication, the stored-program electronic computer, radar, and automatic control systems. In engineering practice, the distinction between electrical engineering and electronics is based on the comparative strength of the electric currents used.
