📌 Most Likely WAEC 2025 Physics Practical Questions
Here are some likely questions and solved answers based on past patterns and WAEC syllabus trends:
✅ 1. Ohm’s Law Experiment
Objective: To verify Ohm’s Law using a resistor, voltmeter, and ammeter.
Apparatus: Ammeter, voltmeter, battery, resistor, switch, connecting wires.
Procedure:
-
Connect the circuit in series.
-
Record current (I) for different voltages (V).
-
Plot a graph of V against I.
Answer Insight:
If the graph is a straight line passing through the origin, Ohm’s Law is confirmed.
Use the slope to calculate resistance:
R = V / I
✅ 2. Determining the Focal Length of a Convex Lens
Objective: To find the focal length using distant object method.
Apparatus: Convex lens, screen, meter rule, and a distant object (e.g. a window).
Procedure:
-
Focus a distant object on the screen.
-
Measure the distance between the lens and screen.
Answer:
That distance ≈ focal length (f) of the lens.
✅ 3. Lever Balance (Principle of Moments)
Objective: Verify the law of moments.
Apparatus: Meter rule, knife edge, weights, and hanger.
Procedure:
-
Balance the meter rule on the knife edge.
-
Add known weights to both sides.
-
Measure distances and apply the moment formula.
Answer:
W₁ × d₁ = W₂ × d₂
