Class 10 Science — Chapter 11: Electricity
68 practice questions · 23 Easy · 23 Medium · 22 Hard
Practise Class 10 Science Chapter 11, "Electricity", with 68 NCERT-aligned multiple-choice questions. The set is split into 23 Easy, 23 Medium and 22 Hard questions, so you can warm up on the fundamentals and then push into the exam-level problems that separate top scorers in CBSE Board exams and the JEE & NEET foundation years.
"Electricity" is one of the chapters where concept clarity across physics, chemistry and biology basics really pays off. Each MCQ on this chapter is timed and uses exam-grade marking (+2 correct, −1 wrong, 0 skipped), training the same accuracy-under-pressure that real papers demand. Every question carries a short explanation, so a wrong answer becomes a quick lesson rather than a dead end — the fastest way to close gaps before a test.
Use this chapter as targeted revision: attempt the Easy set first to confirm your basics on Electricity, then move to Medium and Hard to test application and problem-solving. Your accuracy, streaks and XP save automatically, and the chapter feeds into your overall Class 10 Science mastery score. A few sample questions are shown below; sign in free to practise all 68.
Key concepts: Electricity (Class 10 Science)
This chapter relates electric current, potential difference and resistance through Ohm's law, and covers combinations of resistors and the heating effect of current.
- Current and potential difference
- Current is the rate of flow of charge; potential difference (voltage) drives the current around a circuit.
- Ohm's law
- At constant temperature, the current through a conductor is directly proportional to the voltage across it (V = IR).
- Resistance and resistivity
- Resistance opposes current; it increases with length, decreases with cross-sectional area, and depends on the material (resistivity) and temperature.
- Series and parallel
- In series the same current flows; in parallel the same voltage applies across each resistor.
- Heating effect & power
- Current produces heat (Joule heating); electric power can be found from V, I and R; energy is billed in kilowatt-hours.
Key formulas — Electricity
💡 Exam tips for Electricity
- Series → current is common; parallel → voltage is common. Choose the formula that uses the common quantity.
- Total resistance in parallel is always smaller than the smallest individual resistor.
Sample questions
The SI unit of electric current is:
1 ampere = 1 coulomb per second.
A 220 V appliance draws 2 A. Its resistance is:
R = V/I = 220 / 2 = 110 Ω.
A 1500 W heater runs for 2 hours. Energy consumed (in kWh) is:
E = P × t = 1.5 kW × 2 h = 3 kWh.
