ICSE Class 10 Electricity and Magnetism — Mock Test (2027)
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.Kilowatt hour is commercial unit of :
- a.heat energy
- b.mechanical energy
- c.power
- d.electric energy
-
2.When current flows through a bulb, the wires connected to it do not glow, but the filament does. Why does this happen?
- A.The wires have higher resistance than the filament.
- B.The wires are made of a material that does not heat up.
- C.The wires have low resistance, producing less heat ($H = I^2 Rt$).
- D.The current through the wires is lower than through the filament.
-
3.By reversing the direction of current in an electromagnet, the magnetic field produced by it
- A.remains unchanged in strength and direction.
- B.gets reversed in direction.
- C.increases in strength.
- D.decreases in strength.
-
4.State Fleming's left hand rule for determining the direction of force on a current-carrying conductor placed in a magnetic field. Which of the following correctly describes this rule?
- A.Stretch the forefinger, central finger, and thumb of the left hand mutually perpendicular. The forefinger points in the direction of the magnetic field, the central finger in the direction of current, and the thumb in the direction of force.
- B.Stretch the forefinger, central finger, and thumb of the right hand mutually perpendicular. The forefinger points in the direction of current, the central finger in the direction of the magnetic field, and the thumb in the direction of force.
- C.Stretch the forefinger, central finger, and thumb of the left hand mutually perpendicular. The forefinger points in the direction of force, the central finger in the direction of current, and the thumb in the direction of the magnetic field.
- D.Stretch the forefinger, central finger, and thumb of the left hand in the same plane. The forefinger points in the direction of the magnetic field, the central finger in the direction of force, and the thumb in the direction of current.
-
5.The circuit diagram below is used to verify Ohm's law. Identify the labelled component marked 'X' in the diagram:
.- A.Ammeter (measures current in series)
- B.Rheostat (adjusts resistance in the circuit)
- C.Voltmeter (measures potential difference across component)
- D.Battery (provides constant potential difference)
