Physics for the JAMB Exam
JAMB Physics is required for engineering, computer science, and physical science admissions. Questions test understanding of mechanics, electricity, optics, waves, and modern physics. The CBT format rewards candidates who can quickly identify the right formula and substitute values accurately.
Locale-specific study guides
Pass-rate data, regulatory context, and study tips for Physics all change by candidate locale. Pick your context:
Common failure modes
These are the patterns that cause most candidates to lose marks on this topic. Recognising them in advance is half the work.
- !Substituting values without converting units (e.g., using cm instead of m in mechanics formulas)
- !Confusing the direction of conventional current vs electron flow
- !Misidentifying the type of image formed (real/virtual, erect/inverted) for lenses and mirrors
Study tips
- 1Build a formula card for each JAMB Physics topic — mechanics, electricity, optics, waves, modern physics.
- 2Practice unit conversions daily: cm to m, g to kg, °C to K, eV to Joules.
- 3For optics, practise tracing ray diagrams for concave/convex mirrors and lenses for all object positions.

A 60W bulb is used for 5 hours. The electrical energy consumed is:
- A300 J
- B300 WhCorrect
- C1080 kJ
- D12 kWh
Why this answer?
Energy = Power × Time = 60 W × 5 h = 300 Wh. In joules: 300 × 3600 = 1,080,000 J = 1080 kJ. The question lists "300 Wh" as an answer, which is correct and more directly derived.
