Mini practice paper: 8 questions

Mixed-difficulty questions from across the Physics syllabus. Tap "Show answer" after each to check yourself.

Q1 · Difficulty 1/3

A resistor has a potential difference of 12 V across it and a current of 3 A flowing through it. What is its resistance?

  1. A. 36 Ω
  2. B. 15 Ω
  3. C. 4 Ω
  4. D. 0.25 Ω
Show answer & explanation
✓ Answer: C — C. 4 Ω
Using Ohm's Law, R = V/I = 12/3 = 4 Ω. Option A results from multiplying V and I, option D from dividing I by V, and option B from adding V and I — all common student errors.
Q2 · Difficulty 1/3

What is electric current?

  1. The resistance in a circuit
  2. The flow of electric charge (electrons) through a conductor
  3. The voltage of a battery
  4. The power of a device
Show answer & explanation
✓ Answer: B — The flow of electric charge (electrons) through a conductor
Electric current is the rate of flow of electric charge. In metal conductors, current is the flow of electrons. Measured in amperes (A).
Q3 · Difficulty 1/3

What is the formula for speed?

  1. Speed = distance × time
  2. Speed = distance ÷ time
  3. Speed = time ÷ distance
  4. Speed = force × mass
Show answer & explanation
✓ Answer: B — Speed = distance ÷ time
Speed = distance ÷ time. It measures how fast something is moving, in units of m/s or km/h.
Q4 · Difficulty 1/3

Which statement correctly distinguishes between scalars and vectors?

  1. Scalars have units; vectors do not have units
  2. Scalars can be negative; vectors are always positive
  3. Scalars have magnitude only; vectors have both magnitude and direction
  4. Scalars are measured with rulers; vectors are measured with balances
Show answer & explanation
✓ Answer: C — Scalars have magnitude only; vectors have both magnitude and direction
Award 1 mark for correct distinction. A is incorrect — both scalars and vectors can have units. B is incorrect — both scalars and vectors can be positive or negative. D is incorrect — measuring instruments are not the defining difference between scalars and vectors.
Q5 · Difficulty 1/3

What is the difference between AC and DC?

  1. They are the same
  2. AC changes direction periodically; DC flows in one direction only
  3. DC changes direction; AC does not
  4. AC is only used in batteries
Show answer & explanation
✓ Answer: B — AC changes direction periodically; DC flows in one direction only
Alternating current (AC) continuously reverses direction (mains electricity). Direct current (DC) flows in one direction only (batteries).
Q6 · Difficulty 1/3

What is the difference between series and parallel circuits?

  1. There is no difference
  2. In series, components share one path; in parallel, current has multiple paths
  3. Parallel circuits have more resistance
  4. Series circuits are always brighter
Show answer & explanation
✓ Answer: B — In series, components share one path; in parallel, current has multiple paths
In series circuits, current follows one path through all components. In parallel circuits, current splits into multiple paths — each component gets the full supply voltage.
Q7 · Difficulty 1/3

A technician at a bauxite processing plant in Jamaica is selecting wire for an electrical circuit. Which of the following correctly states the relationship between the resistance of a wire and its length?

  1. Resistance is directly proportional to length
  2. Resistance is inversely proportional to length
  3. Resistance is independent of length
  4. Resistance is proportional to the square of length
Show answer & explanation
✓ Answer: A — Resistance is directly proportional to length
Award 1 mark for stating that resistance is directly proportional to length. B is incorrect because increasing length increases resistance, not decreases it. C is incorrect because length is a factor affecting resistance. D is incorrect because the relationship is linear, not squared.
Q8 · Difficulty 1/3

Which of the following correctly states Ohm's Law?

  1. A. The current through a conductor is inversely proportional to the potential difference across it at constant temperature.
  2. B. The potential difference across a conductor is directly proportional to the current through it at constant temperature.
  3. C. The resistance of a conductor increases proportionally with the current through it.
  4. D. The power dissipated in a conductor is directly proportional to the current through it.
Show answer & explanation
✓ Answer: B — B. The potential difference across a conductor is directly proportional to the current through it at constant temperature.
Ohm's Law states that the potential difference (V) across a conductor is directly proportional to the current (I) through it, provided temperature and other physical conditions remain constant. This gives the relationship V = IR. Options A, C, and D misrepresent the law.
