Candidates’ inaccurate readings translated into their inability to draw the graphs correctly. Some candidates having obtained readings were unable to express them in correct units.

  Suggested Remedies
To remedy this weakness, it is suggested that:

• candidates should be exposed to many practice exercises;         
• qualified technical teachers are required to expose the candidates to the effective use of electrical measuring instruments;
• schools should source for equipment meant for the purpose of practice and examination for the candidates.
