Electronics

Why Electronics?

Many companies today such as Sony, Bosch and Ford require employees with an understanding of and skills in electronics.  The field of electronics is also very important in medicine and in computer and communication industries.  Electronics engineers are very much in demand as there is a significant shortage of qualified people at the present time.

The WJEC Eduqas A level in Electronics will ensure that learners have the electronic and mathematical knowledge and electronic engineering skills to solve problems. This should enable learners to appreciate how many problems in society can be tackled by the application of the scientific ideas in the field of electronics using engineering processes.

Summary of content

There are four core concepts built into the specification that are developed and assessed through three components. The core concepts are:

1.    System synthesis

This topic looks at how to represent systems in terms of inputs, processes, outputs and feedback. This will enable complex systems to be represented in terms of subsystems to allow the communication of complex systems.

2.    DC Electrical circuits

This topic covers basic circuit theory. It involves the study of the resistance of an electronic circuit and its relationship with current and potential difference. Resistors and capacitors connected in series and parallel are also explored.

3.    Input and output sub-systems

This topic covers how input components can be used to give systems useful information about their environment and the type of outputs the system can control.

4.    Energy and power

This topic involves the study of power in DC and AC circuits and the relationship between potential difference, current and power.
