Section A — Objective
Question 1
The instrument used to measure electric current is the
- A. Voltmeter
- B. Ammeter
- C. Galvanometer
- D. Ohmmeter
Answer: B. An ammeter measures current (connected in series). A voltmeter measures potential difference (in parallel).
Question 2
According to Ohm’s law, the current through a conductor is
- A. Directly proportional to the potential difference
- B. Inversely proportional to the potential difference
- C. Independent of the potential difference
- D. Equal to the resistance
Answer: A. Ohm’s law states I ∝ V (at constant temperature), i.e. V = IR.
Question 3
Two resistors of 3 Ω and 6 Ω are connected in series. The total resistance is
- A. 9 Ω
- B. 2 Ω
- C. 18 Ω
- D. 3 Ω
Answer: A. In series, resistances add: R = 3 + 6 = 9 Ω.
Question 4
The energy possessed by a body due to its motion is called
- A. Potential energy
- B. Kinetic energy
- C. Chemical energy
- D. Thermal energy
Answer: B. Kinetic energy (½mv²) is energy due to motion; potential energy (mgh) is due to position.
Question 5
The angle of incidence is equal to the angle of reflection. This is a statement of
- A. The law of reflection
- B. Snell’s law
- C. Ohm’s law
- D. Hooke’s law
Answer: A. The laws of reflection state that i = r and that all three rays lie in the same plane.
Question 6
The unit of power is the
- A. Joule
- B. Watt
- C. Newton
- D. Volt
Answer: B. Power (rate of doing work) is measured in watts (1 W = 1 J/s).
Section B — Theory
Question 1 — Theory
State the laws of reflection of light.
Answer: (1) The incident ray, the reflected ray and the normal all lie in the same plane. (2) The angle of incidence equals the angle of reflection.
Question 2 — Theory
A body accelerates from 5 m/s to 25 m/s in 4 s. Calculate its acceleration.
Answer: a = (v − u)/t = (25 − 5)/4 = 20/4 = 5 m/s².
