_Texts: Dawes, “Electrical Engineering”, Vol. I & II; Peet, “Laboratory Manual in Electricity”._ EE 31 Electric Networks. For the purpose of making analyses of electric networks the following principles are introduced: Algebra of Complex Quantities Kirchhoff’s Laws “T” to “Pi” transformation Thevenin’s Theorem Superposition Theorem Magnetic and dielectric coupling Resonance _Text: Everitt, “Communication Engineering”; Fishman, “Electric Circuit Projects”._ EE 32 Electric Transients. The transient conditions existing in direct and alternating current circuits whenever the current values are suddenly changed are of great importance in many electrical problems. To investigate these an analysis is made of the time variation of energy, power, current and voltage whenever there is a readjustment of energy in these circuits. The analysis is made for circuits in which energy is stored in either magnetic or dielectric form or in both forms. _Text: Fishman, “Electric Circuit Projects”._ EE 33 Electric Machinery. Prerequisites, EE 21, EE 22. The subject matter of this course is presented in three divisions as follows: a. A study of direct-current generator and motor characteristic curves, separation of losses, regulation and efficiency, parallel operation, three-wire and pump-back tests, armature reaction and commutation. b. A similar study of alternating current machinery includes transformers, alternators, synchronous and asynchronous polyphase motors, single-phase motors and converters. c. Armature windings: development from elementary coil of both ring and drum types; representation of both open and closed circuit winding by circular diagrams, tables and vector diagrams; bipolar and multipolar, simplex and multiplex windings; phase distribution and distribution factors. An extensive laboratory course supplements the class work. _Texts: Dawes, “Electrical Engineering”, Vol. I & II; “Standard Handbook for Electrical Engineers” (Sixth Edition); Nims, “Armature Winding Notes”, Fishman and Shedd Laboratory Manual “Electric Machinery”._ EE 35 Electron Tubes. Prerequisites, EE 21, EE 22. A study is made of the following electronic devices: Volt-ampere characteristics of contact rectifiers. Illumination-response of photo-sensitive devices (conductive, voltaic, vacuum and gas emissive cells). Emission from tungsten, thoriated tungsten and oxide-coated cathodes. Characteristics and coefficients of vacuum diodes, triodes and multigrid tubes. The electron gun. Ignition and volt-ampere characteristics of cold cathode, hot cathode, and pool cathode gas and vapor tubes. Methods of controlling output of gas and vapor tubes by means of grids. _Texts: Fishman, “Electronics Laboratory Projects”._ EE 41 Electric Transmission Equipment.
