As the JEE Main 2026 session 1 (January) is near, candidates should ensure they have completed the high-weightage topics in the Physics section.
- One of the most important topics in Physics, from which an average of 2-4 questions are asked in every shift, is Current Electricity, a topic covered in Physics Class 12, Chapter 3.
- Based on the analysis of JEE Main papers from the last 5 years, most of the questions asked from this chapter are mostly formula-based and direct.

Most Important Current Electricity Topics for JEE Main 2026
- In the Current Electricity chapter, the topic-wise expected weightage varies from 6% to 18% each year, and Series & Parallel Combination of Resistors and Kirchhoff’s Laws (Loop & Junction Rules) has the highest weightage of around 15-18%.
- Topics with lower weightage, such as Electric Power and Energy (6-8%), are not guaranteed to have questions in the JEE Main exam every year.
| Topic | Expected Weightage (%) | Approximate Questions |
|---|---|---|
| Ohm’s Law & V–I Characteristics | 10-12% | 1 |
| Electrical Resistance & Resistivity | 8-10% | 1 |
| Series & Parallel Combination of Resistors | 12-15% | 1-2 |
| Kirchhoff’s Laws (Loop & Junction Rules) | 15-18% | 1-2 |
| Electric Power & Energy | 6-8% | 0-1 |
| Cells, EMF & Internal Resistance | 12-15% | 1 |
| Wheatstone Bridge & Meter Bridge | 8-10% | 1 |
| Potentiometer | 10-12% | 1 |

- Over the past five years, approximately 2-3 questions out of 25 in the physics section have come from this topic in every shift of the exam each year.
Reddit & Student Insights: What Aspirants Say About Current Electricity
The difficulty level of questions from the Current Electricity chapter in the JEE Main exam is primarily determined by the feedback from candidates, which they share on public platforms like Reddit and YouTube. For this chapter, mixed opinions have emerged:
- According to one Reddit user, “the questions on Current Electricity are often confusing because concepts like EMF and potential drop in a circuit seem difficult when solving numerical problems.”

- There's an ongoing debate about covering topics in the Class 12 NCERT Physics book for the JEE Main exam. Some students on Reddit reported following the sequence Electrostatics → Capacitance → Current Electricity. However, another group of students felt that studying Current Electricity before Capacitance helped them understand later topics and solve circuit problems more effectively.

Ques: How to memorise the Current Electricity chapter formulas for a longer time?
Ans: To memorise any concept or formula in Physics, you need to follow the three R's in your study routine: Read, Revise, and Repeat.
- Formula Derivation: Understand the important derivation first, and then you will be able to apply it easily to numerical problems.
- Create a Dedicated Sheet for Formulas: Create a sheet and highlight the important formulas that are frequently asked in exams. Make the sheet handy so that you can revise it regularly.
- Regular Numerical Practice: Practice the important formulas for current electricity in numerical problems.
- Make Others Understand: According to experts, the most effective way to memorise even difficult topics is to explain or teach them to others. Once you feel completely confident, explain the entire derivation to your classmates. This will help you develop long-term memory.
