🔎 What Does the WAEC Physics Practical 2025 Exam Involve?

The Physics Practical tests your hands-on knowledge of Physics concepts through real-life experiments. You’ll need to:

• Take accurate measurements

• Record observations properly

• Use physics formulas to calculate results

• Interpret graphs and data

📌 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
