- 02
48% of its questions since 2020 tested an idea no earlier year had asked; 11 repeated an idea from the year before.
- 03
The most repeated idea is Energy Stored in Inductors, asked 7 times in 7 shifts (2020, 2021, 2022, 2023, 2026), most often as “energy ratio in inductor network”.
- 04
JEE Main has asked 14 of the 61 ideas in this topic; 46 have never been asked, directly or inside another question.
- 05
Mostly asked as numerical value (45%); 45% need a numerical answer, 32% are easy and 19% hard.
- 06
The skill tested most is multi-step (39%), then calculation (39%).
Questions a shift, year by year
Out of the 25 Physics questions in a shift. Years differ in how many shifts Lumi analysed, so each year is scaled to one shift.

New idea, or one asked before?
Each column is a year. Blue questions tested an idea no earlier year had asked; navy ones went back to an idea from an earlier year. 2017 is the first year, so everything in it counts as new. Heights are question counts, and Lumi analysed 1 to 24 shifts a year, so compare the split inside a column rather than heights across years.
- Idea asked for the first time
- Idea asked in an earlier year
Coverage of the topic
JEE Main has asked 14 of the 61 ideas in this topic. 46 have never been asked yet.
- Asked directly14 · 23%
- Touched inside another question1 · 2%
- Never asked46 · 75%
Ideas come from Lumi’s JEE syllabus map. A never-asked idea is not a safe skip: across all of JEE Main, 22% of questions since 2024 tested an idea no earlier year had asked.

Squares are the 8 years with analysed shifts, 2017 to 2026. A number is the questions that year when there is more than one; the shade is scaled to one shift, so a year with more analysed shifts (1 to 24 a year) does not look darker. Share is of the level above.
