- JEE Main Weightage: 3 to 5% (typically 1 to 2 questions per shift)
- NEET Weightage: 2 to 3 questions per year
How the NCERT Exemplar Helps Class 12 Students with Current Electricity
This page gives you the official 2026-27 Exemplar print plus context that a raw PDF does not carry.
- 2026-27 NCERT Alignment: Every problem in the 32-question set maps to a sub-topic still in the current Class 12 Physics syllabus, so you do not waste time on dropped content.
- Question-Type Inventory: A clear count of MCQ-I, MCQ-II, VSA, SA, and LA problems lets you pace each sitting against the actual size of the load.
- Self-Test Format: The book prints problems only, so you can attempt cold, mark weak areas, and return in the final revision week.
- JEE and NEET Crossover: Recent JEE Main and NEET shifts have reused Exemplar setups almost verbatim. Working this Exemplar is the fastest way to lift your Current Electricity entrance score.

Inside the Class 12 Physics Chapter 3 Current Electricity Exemplar Book
The Exemplar has about 6 pages split into five sections. The table below shows where each sub-topic is concentrated, so you can target your weakest area first.
| Sub-Topic | Problem Numbers |
|---|---|
| Drift velocity and Ohm's law microscopic form | 3.1, 3.7, 3.13, 3.18 |
| Resistance, resistivity and temperature dependence | 3.2, 3.5, 3.16, 3.21 |
| Kirchhoff's laws and circuit reduction | 3.3, 3.4, 3.10, 3.22, 3.27 |
| EMF, internal resistance, terminal voltage | 3.6, 3.14, 3.19, 3.23, 3.29 |
| Wheatstone bridge and potentiometer | 3.11, 3.17, 3.25, 3.32 |
Current Electricity Exemplar Question-Type Breakdown for Class 12 Physics
The 2026-27 print divides Chapter 3 into five question types. The split below tells you how many of each kind you face and the indicative marks per question.
| Question Type | Number of Problems | Indicative Marks Each |
|---|---|---|
| MCQ-I (single correct) | 6 | 1 |
| MCQ-II (one or more correct) | 6 | 2 |
| Very Short Answer (VSA) | 10 | 1 to 2 |
| Short Answer (SA) | 6 | 3 |
| Long Answer (LA) | 4 | 5 |
| Total | 32 | - |
MCQ-II is the most-failed type because more than one option can be correct. Treat it as a slow type, not a quick one.
Current Electricity Exemplar vs NCERT Textbook: Difficulty Step-Up
The Exemplar takes the same physics as the textbook but adds one or two harder layers. The contrast below shows what changes between the two books.
| Aspect | NCERT Textbook | NCERT Exemplar |
|---|---|---|
| Purpose | Concept building and solved examples | HOTS practice with multi-step problems |
| Difficulty band | Easy to medium | Medium to very hard (especially LA) |
| Solved examples | Around 6 to 14 solved examples | Zero step-by-step solutions in the book |
| Total practice problems | Roughly 10 end-of-chapter exercises | 32 problems across 5 types |
| Match rate with JEE and NEET | Low to medium | High (around 25 to 30% reused) |
If you can finish only one extra book outside the NCERT textbook for Current Electricity, pick the Exemplar.
Top Formulae for Current Electricity Before Attempting the Exemplar
Most Exemplar problems hinge on a small set of recurring formulas. Lock these into memory before you open the PDF and you will save 30 to 40% of attempt time per problem.
| Concept | Formula |
|---|---|
| Ohm's law (microscopic form) | j = sigma E |
| Drift velocity | v_d = e E tau / m |
| Resistivity dependence | rho = rho_0 (1 + alpha Delta T) |
| EMF and terminal voltage | V = epsilon - I r |

Student Feedback
"The sub-topic table helped me figure out exactly which problems to focus on. I had only one week before my boards and I targeted Kirchhoff's laws problems first." - Class 12 student, Delhi
"MCQ-II used to trip me up every time. After practising the Exemplar, I stopped guessing and started eliminating options properly." - Class 12 student, Pune
"The question-type breakdown told me how many LA problems there were. Knowing it was only 4 made them feel less scary." - Class 12 student, Hyderabad

NCERT Exemplar Class 12 Physics Current Electricity - Frequently Asked Questions
Ques. Where can I download the NCERT Exemplar Class 12 Physics Current Electricity for free?
Ans. You can download the NCERT Exemplar Class 12 Physics Current Electricity directly from this page. The flipbook preview and the one-click PDF download are both free.
Ques. How many questions are in the Class 12 Physics Chapter 3 Exemplar Book?
Ans. Chapter 3 of the Class 12 Physics Exemplar has 32 problems in total: MCQ-I (6), MCQ-II (6), VSA (10), SA (6), and LA (4). The PDF runs approximately 6 pages.
Ques. Is the Exemplar Book PDF aligned with the 2026-27 NCERT?
Ans. The NCERT Exemplar was not rationalised when the textbook was trimmed. Most Chapter 3 problems still map to the current 2026-27 syllabus. A small number touch sub-topics that were removed and can be skipped during board preparation.
Ques. Are Exemplar problems compulsory for the CBSE Class 12 board exam?
Ans. Exemplar problems are not part of the prescribed NCERT textbook, but CBSE has used Exemplar-style HOTS items in 4 of the last 5 board papers. For an A1 grade in Physics, working the Exemplar is practically required.
Ques. Where can I find the solutions to the Current Electricity Exemplar problems?
Ans. Solved answers for every problem in this chapter are on the Current Electricity Class 12 Physics NCERT Exemplar Solutions page.
