You are a trainee laboratory technician working for local aluminium
smelting works. The smelting works is a huge consumer of
electricity and has its own hydroelectric generating plant. The
hydroelectric plant sends excess electricity to the National Grid,
Vocational Scenario or which is in turn distributed to local homes. The plant also has an
Context induction furnace to produce aluminium ingots after the aluminium
has been smelted. As part of your training you have been asked by
the Health and Safety committee of the company to develop an
electrical safety awareness booklet for their employees.
Prepare a booklet titled ‘Electrical Safety Awareness’ that has the
following sections:
Section 1 – AC and DC current
Explain the differences and similarities of the properties of AC and
DC current in simple circuits
How are they produced? Use diagrams based on simple
Task laboratory experiments to illustrate.
Use laboratory based investigations to evaluate how to control
the AC electricity produced by generators. Apply the application
of Flemings’ rules to the operation of an electrical motor (left
hand) and the operation of an AC generator (right hand) to
explain the principles of a DC generator
Describe DC electricity can be stored.
Illustrate, with a fully labelled graph, the difference between
AC and DC electricity using an oscilloscope.
For AC compare the calculated root mean square (RMS)
and measured peak voltage to show the quantitative
relationship of RMS and peak values for AC electricity
Section 2 - Effects of AC and DC electricity on the human
physiology
In the context of the dangers of working with electricity, use a
