SUBJECTS OF INSTRUCTION
in the
DEPARTMENT OF ELECTRICAL ENGINEERING

EE 21 Electricity.

This is the fundamental electrical course for all electrical engineering students. The lecture, class and laboratory method is used. The subject is treated from the point of view of the physicist. The electron theory is the basis. For each phenomenon considered a physical explanation is given as well as a mathematical expression. Particular attention is given to the proper definition of the units of measurement. The relation between these quantities is emphasized by problem work.

Laboratory work in measurements and the proper use of instruments is carried on at the same time.

Texts: Zeleny, “Elements of Electrical Engineering”; Peet, “Laboratory Manual in Electricity”.

EE 22 Electric Circuits.

This is a lecture, recitation and laboratory course in the fundamental electrical units and their proper application to the usual direct current and alternating current circuits. It is given to all electrical students in the second semester of the sophomore year.

A general list of the topics is as follows: Magnetism, electro-magnetism; electric current, pressure and resistance; electric power and energy; series, parallel and series parallel circuits; Kirchhoff’s law; three-wire system; electro-statics; dielectric circuit; alternating current circuits containing resistance, inductive reactance and capacitive reactance in series and parallel combinations by graphical, analytical and complex quantity methods; single and polyphase alternating current circuits.

Laboratory work in direct-current and constant frequency alternating current circuits supplements the classroom work.

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:

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. Prerequisite, Satisfactory Senior Standing.

The accessory apparatus for the production of electric power, and its transmission and distribution to the consumer is the basis of a seminar type course. Each student investigates an assigned topic in some detail and discusses his findings for the information of the class. Prime movers, generator excitation and voltage regulation, feeder voltage regulation, station wiring layouts, switchboards and switching gear, reactors, relays and relay systems, line disturbances and line protection, plant economics and energy rates, industrial motor application and control are topics treated.

Text: “Standard Handbook for Electrical Engineers” (Sixth Edition).

EE 42 Electric Transmission Circuits. Prerequisites, EE 31, EE 32.

Aspects of electric power transmission which are subject to analytical attack are treated by lecture and computation methods.

The topics included are: Calculation of short lines, low voltage distribution, conductor materials, spacing, corona effect, economic voltage and frequency, hyperbolic functions and the calculation of line constants, calculation of long lines by graphical, approximate and rigorous methods, comparison of methods, synchronous machines for power factor and voltage control, effect of transformers included in circuit regulation.

Text: Woodruff, “Electric Power Transmission and Distribution”; Everitt, “Communication Engineering”.

EE 43 Electric Machinery. Prerequisite EE 33.

A continuation of Electric Machinery EE 33.

EE 45 Electrical Measurements. Prerequisites, EE 31, EE 32.

This is mainly a laboratory course illustrating some of the more advanced problems in electric circuits. In the associated classroom work the principles underlying the laboratory problems are discussed and the quantitative relations emphasized. The projects considered fall under the general heading of Measurement Circuits:

Text: Nims, “Advanced Circuits Measurements Manual”.

EE 46 Electron Tube Circuits. Prerequisites, EE 35, EE 45.

A continuation of EE 45, dealing principally with the following topics:

Texts: Everitt, “Communication Engineering”; Nims, “Advanced Circuits Measurements Manual”.

EE 47 (EE 47-1, 47-2) Electrical Design. Prerequisites, EE 22, EE 33.

The performance characteristic of electric equipment depend upon the materials of which it is made, and upon the arrangement and dimensions of these parts. In this course this relationship for simple equipment, such as resistors and magnets, is studied mainly by computation methods. Some time is taken here for the layout of machinery locations on the floors of a building, which gives some practice in the use of surveying instruments. The quantitative study of materials and their arrangement in electric machinery is carried further into the windings of direct and alternating current machinery, including transformers if time is available.

Texts: Nims, “Electric Machine Design Notes”; Busse, “Surveying Notes”.

EE 71 Electricity.

This is the general course adapted to the needs of chemical and mechanical engineering students.

It is a lecture, recitation and problem course in the fundamental units and their application to the electric circuits and machines.

The topics are as follows: Magnetism, induction, electric current, pressure and resistance, electric power and energy; electric, magnetic and electro-static circuits; single and polyphase alternating current circuits by graphical, analytical and complex quantity methods.

Texts: Dawes, “Electrical Engineering”, Vol. I; Dawes, “Electrical Engineering”, Vol. II; McKone, Laboratory Manual “Applied Electricity”.

EE 75 Electricity.

This is a general survey course adapted to civil engineers. It is not followed by laboratory experience. It treats the fundamental units and their application to electric circuits and electric machinery, both direct and alternating current. It is made as broad as possible for these students who have but limited time to give to the subject.

Text: Timbie, “Elements of Electricity”.

EE 81 Applied Electricity. Prerequisite, EE 71.

This is the electric machinery course for mechanical engineering students. It offers experience in the wiring, measurement and operation of the usual direct and alternating current machines. The proper application of these machines in industry is treated.

The classroom work is supplemented by a machine laboratory course.

Texts: Dawes, “Electrical Engineering”, Vols. I & II; McKone, Laboratory Manual “Applied Electricity”.

EE 83 Applied Electricity. Prerequisite, EE 71.

This is the electric machinery course for chemical engineering students. It is similar to EE 81 except that it requires but one semester and therefore is much abridged.
