The process of building a circuit

Part A (20 marks)
Prepare and deliver a five-minute commentary on a topic given below, in which you will record and submit an
audio recording as part of your assignment. The commentary should be an audio recording. Tutors will only
mark the submitted commentary, they will not mark performances. Note marks are awarded only for the
technical content of the commentary, however if the recording cannot be accessed a “0” mark will be given.
This means that recordings taken on a mobile phone are acceptable, but please ensure that the commentary is
clearly audible before submitting and in a format that is accessible. You should upload to Moodle a word
document which contains a link to the audio file, which itself should be uploaded into the cloud using your
Microsoft One Drive, and made available for your tutors to access.
Part B (20 marks)
Describe the process of building the circuit, simulate the circuit in Multisim, include images of the simulation in
your report and analyse the experiment. If you do not complete this section you will receive a “0” mark. Please
ensure the simulation is saved in a separate file with the question number and appropriate name as part of the
file name. This file needs to be included in the Microsoft One Drive folder of which link you copied in Part A,
and shared with all the tutors.
Answer all questions. You will be required to design and simulate electric circuits using the industry-standard
software, Multisim. Please ensure that each different simulation is saved in separate file with the question
number and appropriate name as part of the file name. These files need to be included in the Microsoft One
Drive folder of which link you copied in Part A, and shared with all the tutors. The report which contains your
worked solutions and explanations (including Part A and Part B)
SummaryPart A (20 marks)
Prepare and deliver a five minute commentary on how the electrons move when a voltage is applied to a P-N
junction, and explain how this relates to a diode.
Also acknowledge all resources used in the commentary according to CU Harvard referencing style (both the
ones that you mention in the commentary and the ones in which you have read and found relevant
information).
Part B (20 marks)
Simulate and represent how to display the voltage discharging curve across the capacitor in a R-C circuit and
explain the process behind it in this report with the aid of screenshots and calculations (equations). Your circuit
must aim to achieve a time constant based on the second to last digit of your student ID (Table 1). The circuit
must be simulated in Multisim.

In the report include an explanation of the component values used (and why), screenshots of the instruments
and Multisim simulation and acknowledge all resources used for the explanation (informing your background
knowledge).
