Current Electricity

Test Your Knowledge

To calculate your current grade in this subject area, give yourself a confidence score for how well you think you would answer each of the questions below in an exam situation.

These are not the type of questions you would typically find in a physics exam. They are designed to remind you which topics you need to revise.

For scoring, 4= Very confident, 0= No Idea. If a question is not on your syllabus, click N/A and you will not be graded on it.
