Think through six short scenarios
Six topic-specific scenarios, explained answers and links to related lessons. This short practice supports learning; it is not a proficiency examination.
This practice is not an examination or a certificate of mastery. Focus on the reasoning and return to the related lesson when uncertain.
Topics you will practise
Try the questions
Safety
Use only low-voltage educational equipment for electronics activities. Never work on mains electricity.
If you want to see the answers
Each answer and explanation appear here after you submit your response. To read every question together with its reasoning on one page, see the Worked Study page, which reads without JavaScript and does not keep a score.
Follow your result with practice
Change one condition in a question and explain whether the answer changes. Would you make the same decision with a different value, boundary or source? Recognising an answer is not the same as explaining it in a new situation.
References and records

Selected-question reviews are not the same as full sessions. “Full-session best” on the progress page uses only sessions containing all six questions. A suggested review date is a reminder, not a scientifically personalised study schedule.
