Identify a number of common
electronic components that are shown to you. Explain, in simple terms, the
functions they perform in electronic circuits.
Describe the systems used for
marking components with their values. Demonstrate by identifying the values
of resistors and capacitors by their markings. Explain the importance of the
rating of a component.
Show that you know the symbols
used to represent common components in circuit diagrams. Show how to
identify the polarity of a diode and a specific pin number on an integrated
Show that you’re aware of the safe
working practices to be followed when handling electronic components,
circuit boards and when soldering.
Use a multimeter to measure
voltage, current and resistance in a simple circuit. Explain the
relationship between these values.
Talk about the main differences in
the operation of digital and analogue circuits.
Construct three simple circuits.
One of these should be based mainly on digital electronics. They can be from
a book or magazine, or you can design the circuits yourself. If possible, at
least one of the circuits should be soldered using either stripboard or a
custom-made printed circuit board.
Explain the principles behind the
operation of each circuit and the typical values of voltage and current
found in each.
Explain the possible uses of the
three circuits you built.
Talk about the uses and benefits of electronics in everyday life. Explain how electronics can be used to
