Free online mock test for Electricity and Magnetism (ICSE Class 10 Physics) — 20 competency-based questions based on the latest CISCE 2027 syllabus, with instant marking. Try the samples below, then take the full test free.
What to expect: This mock test covers key concepts from the Electricity and Magnetism chapter — including application-based and competency-focused questions aligned with how ICSE actually sets the paper.
Tip: Attempt without notes first to identify gaps, then review explanations for any wrong answers. Retake after a few days for best retention.
Sample questions
-
1.The main fuse is connected in
- A.live wire
- B.neutral wire
- C.both the live and earth wires
- D.both the earth and neutral wires
-
2.Which of the following factors will increase the speed of rotation of the coil in a D.C. motor?
- A.Decreasing the number of turns of the armature.
- B.Increasing the applied battery e.m.f.
- C.Reducing the strength of the magnetic field.
- D.Using a thinner wire for the armature coil.
-
3.The resistance of a wire is 20 Ω at 20°C. If its resistance increases to 25 Ω at 100°C, why does this happen?
- A.The wire's length increases with temperature, raising its resistance.
- B.Higher temperature causes more electron collisions, increasing resistance.
- C.The wire's cross-sectional area decreases, reducing resistance.
- D.Resistance decreases because electrons move faster at higher temperatures.

4.Assertion: A resistor of resistance R is connected to an ideal battery. If the value of R is decreased, the power dissipated in the circuit will increase. Reason: The power dissipated in the circuit will increase. (a) Both assertion (A) and reason (R) are true and reason (R) is the correct explanation of assertion (A). (b) Both assertion (A) and reason (R) are true but reason (R) is not the correct explanation of assertion (A). (c) Assertion (A) is true but reason (R) is false. (d) Assertion (A) is false but reason (R) is true.
- A.Both assertion (A) and reason (R) are true and reason (R) is the correct explanation of assertion (A).
- B.Both assertion (A) and reason (R) are true but reason (R) is not the correct explanation of assertion (A).
- C.Assertion (A) is true but reason (R) is false.
- D.Assertion (A) is false but reason (R) is true.

- A.The branch containing only the 8 Ω resistor
- B.The section where the 6 Ω and 12 Ω resistors are connected side-by-side
- C.The entire loop including the 8 Ω resistor and the battery
- D.The junction point between the 8 Ω resistor and the 6 Ω resistor
