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.Why cannot a transformer be used with a direct current (d.c.) source?
- A.A d.c. source produces a constant magnetic field, which does not induce an e.m.f. in the secondary coil.
- B.A d.c. source causes the transformer core to overheat due to excessive resistance.
- C.A d.c. source reverses the polarity of the magnetic field too rapidly for induction.
- D.A d.c. source generates a magnetic field that cancels out the secondary coil's field.
-
2.If the resistance of a wire is 12 Ω and the current flowing through it is 0.5 A, what is the potential difference across its ends?
- A.24 V
- B.6 V
- C.3 V
- D.-6 V
-
3.Why is it more economical to transmit electrical energy at high voltage and low current?
- A.Energy loss is proportional to the square of current, so low current reduces loss
- B.High voltage increases the speed of electricity
- C.Low current eliminates the need for transformers
- D.High voltage makes the transmission lines lighter
-
4.Calculate the equivalent resistance of the circuit as shown in figure, in which six equal resistances of 1 ohm each are connected in hexagonal form.
-
5.Four resistors each of resistance 2 Ω are connected in parallel. What is the effective resistance?
- A.0.5 Ω
- B.8 Ω
- C.1 Ω
- D.0.25 Ω
