Section B: True or False (5 × 1 mark = 5 marks)

Write “T” for true or “F” for false.

  1. Ammeters are always connected in parallel with the load. _____
  2. Copper wire is an insulator. _____

  5. A short circuit has very high resistance. _____

Section E: Calculation Problems (8 marks)

Use Ohm’s Law (V = I × R) to solve.

  1. (3 marks) A hair dryer draws 5 A of current when connected to a 120 V outlet. What is the resistance of the hair dryer?

  2. (5 marks) A 6V battery is connected to two parallel resistors: 3Ω and 6Ω.
    a) (2 marks) Calculate the total resistance of the parallel combination.
    b) (3 marks) Calculate the total current supplied by the battery. f2 science electricity exercise top

  4. In a ___________ circuit, components are connected across the same two points.
  5. The energy per unit charge is called ____________.

Why F2 Students Struggle with Electricity

Before diving into the exercises, let us diagnose the three biggest pain points:

  1. Current vs. Voltage: Mixing up flow (current) with push (voltage).
  2. Series vs. Parallel: Memorizing rules without understanding why bulbs dim or stay bright.
  3. Drawing Circuits: Forgetting the ammeter must be in series, and the voltmeter must be in parallel.

The top exercise below is designed to fix these three problems. Ammeters are always connected in parallel with the load
