Work, Energy and Power — JAMB Physics Past Questions
Work, Energy and Power is one topic inside the JAMB Physics syllabus, and drilling it on its own is usually faster than revising the whole subject again. Below: which JAMB years have examined it, then real Work, Energy and Power questions with worked answers.
When JAMB examined Work, Energy and Power
Work, Energy and Power questions appear in our bank for the JAMB years below. This is taken from the questions themselves, not from a syllabus outline — so if a year is listed, this topic was genuinely examined that year.
A topic that keeps reappearing is a topic JAMB keeps testing. Newer years matter most, because question style drifts.

The ______ is a basic unit of work or energy.
- A Watt
- B Joule
- C Kelvin
- D Tesla
Answer: B
The joule (J) is the SI unit of work and energy. It is defined as the work done when a force of one newton displaces an object by one meter.
The power dissipated by a resistance is directly proportional to ______.
- A V²
- B I²
- C V
- D A & B
