Prerequisites

Students considering registering for this course must have attained passes in A-levels or the equivalent that meet the minimum requirements for admission onto the undergraduate programmes in Mechanical Engineering.

Course Aims

To provide students with fundamental skills in the analysis of basic ac and dc circuits, to give an understanding of the wider role electricity has in society and the interaction between mechanical engineering and electrical engineering and to enable students in undertaking simple electrical experiments with confidence.

Students who complete this course will be able

  • To carry out fundamental analysis for dc and ac circuits
  • To be able to use electrical instrumentation competently
  • To understand the operation of electrical machines
  • To be able to construct basic electrical and electronic circuits.

Method of Instruction

Lecture presentations, tutorial classes, and laboratory classes.

Assessment

The course has the following assessment components:

  • Written Examination (3 hours, 75%)
  • Christmas Test (33%)
  • Two Laboratories (66%)
  • Obtain an overall pass mark of 40% for all sections combined

Recommended Reading
