HSC Physics Question Bank with Important Questions – Current Electricity 2026
Preparing for the Maharashtra Board HSC exams can feel like a daunting task, especially with subjects like Physics that require both conceptual clarity and mathematical precision. For the academic year 2026, Current Electricity remains a cornerstone of the syllabus. This chapter is not just a high-weightage unit for the board exams but also a vital component for competitive exams like NEET and JEE.
In this comprehensive guide, we provide a structured HSC Physics Question Bank with Important Questions – Current Electricity 2026, analyzed from previous year patterns and the latest official SCERT guidelines. Whether you are aiming for a medical career or engineering, mastering this chapter is non-negotiable.
Understanding the 2026 Exam Pattern and Weightage
Before diving into the questions, it is essential to understand how much weight this chapter carries. According to the latest MSBSHSE marking scheme:
Weightage without Options: 4 Marks
Weightage with Options: 6 Marks
The questions are typically distributed across Multiple Choice Questions (MCQs), Very Short Answers (VSA), and Long Answer (LA) derivations. For students aiming for medical entrance exams, the conceptual understanding of Kirchhoff’s Laws and Potentiometers is crucial, as these topics appear frequently in competitive physics sections.
Important Concepts and Theory Questions
To score high, you must focus on the most repeated theory questions. These are curated based on the HSC Physics Question Bank with Important Questions – Current Electricity 2026 trends.
1. Kirchhoff’s Laws of Electricity
State and explain Kirchhoff’s First Law (Current Law/Junction Law).
State and explain Kirchhoff’s Second Law (Voltage Law/Loop Law).
Note: These laws are the foundation of circuit analysis and are frequently asked as 2-mark questions.
2. Wheatstone Bridge and Meter Bridge
Obtain the balancing condition for a Wheatstone Network using Kirchhoff’s Laws.
Describe with a neat circuit diagram how a Meter Bridge is used to determine an unknown resistance.
Explain the sources of errors in a Meter Bridge experiment and how to minimize them.
3. Potentiometer: The Most Important Topic
Define Potential Gradient and state its SI unit.
Explain the principle of a Potentiometer.
Describe how a Potentiometer is used to compare the EMF of two cells using the:
Individual Method
Sum and Difference Method
Explain the use of a Potentiometer to determine the internal resistance of a cell.
Medical Relevance: Potentiometers are preferred over voltmeters for precision in sensitive measurements—a concept often tested in medical entrance exams.
4. Galvanometer Conversions
How is a Moving Coil Galvanometer (MCG) converted into an Ammeter? Derive the formula for the shunt resistance.
How is a Moving Coil Galvanometer converted into a Voltmeter? Derive the formula for the series resistance.
Distinguish between an Ammeter and a Voltmeter.
Essential Formulas for Revision
In the 2026 exam, numericals will contribute significantly to your score. While you should practice the calculations, memorizing the following formula names is the first step:
Ohm’s Law Relationship
Kirchhoff’s Current and Voltage Algebraic Sums
Balancing Condition of Wheatstone Bridge
Meter Bridge Unknown Resistance Formula

FAQ Section
Q1: Where can I find the official HSC Physics Question Bank with Important Questions – Current Electricity 2026?
A1: The official question banks (Prashnapedhi) are released by SCERT Maharashtra on their official portal (maa.ac.in). You can also find previous year papers on the MSBSHSE website.
Q2: Is "Current Electricity" important for NEET 2026 aspirants?
A2: Yes, absolutely. It is one of the highest-weightage chapters in the Physics section of medical entrance exams. Concepts like the Potentiometer and Kirchhoff’s Laws are favorites among examiners.
Q3: How many marks can I expect from this chapter in the 2026 Board Exam?
A3: You can expect approximately 4 to 6 marks. Usually, there is one MCQ, one short answer, and one 3-mark derivation or numerical.
Q4: Why is a potentiometer preferred over a voltmeter?
A4: A potentiometer is a null-point instrument and does not draw any current from the source, providing an accurate measurement of EMF. A voltmeter draws some current, leading to a slight drop in the measured potential.
