WAEC GCE Basic Electricity 2025 Theory Practice Questions

Question 1

(a) Define resistance in an electrical circuit.
(b) State Ohm’s Law.
(c) If a current of 2A flows through a resistor of 10Ω, calculate the potential difference across it.

Answer Guide:

  • (a) Resistance is the opposition to the flow of current in an electrical circuit.

  • (b) Ohm’s Law: Voltage (V) = Current (I) × Resistance (R).

  • (c) V = IR = 2 × 10 = 20V.

Question 2

(a) Differentiate between series and parallel circuits.
(b) State two advantages of parallel circuits over series circuits.

Answer Guide:

  • In series circuits, current is the same through all components, but in parallel, voltage is the same across all branches.

  • Advantages of parallel circuits:

    1. If one component fails, others still work.

    2. Each device receives the same voltage.

Question 3

(a) State three safety precautions when handling electrical appliances.
(b) Why is earthing important in domestic wiring?

Answer Guide:

  • Safety precautions:

    1. Always switch off appliances before repair.

    2. Use insulated tools.

    3. Avoid water contact while handling electricity.

  • Earthing prevents electric shock by directing leakage current safely into the ground.
