In IB Physics First Assessment 2016, power generation and transmission is a subtopic of Topic 11, electromagnetic induction. This subtopic has the following understandings associated with it.
- Alternating current (AC) generators
- Average power and root mean square (RMS) values of current and voltage
- Transformers
- Diode bridges
- Half-wave and full-wave rectification
In this part of the analysis, I am particularly interested in “What is the frequency distribution of the questions concerning power generation and transmission understandings?”
Frequency distribution of questions by power generation and transmission for HL
Between 1999-2023
For the entire dataset for HL, average power and root mean square (RMS) values of current and voltage accounted for about two-fifths of the questions. One-third of the questions came from transformers. Rectification and diode bridges accounted for less than one-tenth of the questions.

Between 2016-2023
Between these years, the significant change is the increased emphasis on rectification and diode bridges.
