ELECTRICAL SAFETY
4.4 Boss Fight Quiz - Cambridge IGCSE Physics 0625
⚠️ SAFETY FIRST MINDSET
This quiz tests your ability to PREVENT electric shocks, fires, and equipment damage. In real life, getting these concepts wrong can be FATAL. Master this topic!
PAPER 2: MULTIPLE CHOICE QUESTIONS
Select the BEST answer for each question.
Which wire in a mains plug MUST the fuse be connected to?
What is the international symbol for double insulation?
What is the color of the NEUTRAL wire in a UK mains plug?
A 3kW kettle operates on 240V mains supply. What is the minimum safe fuse rating?
Which of these is NOT a hazard when using mains electricity?
🎯 EXAM STRATEGY RECAP
- •Paper 2: Eliminate obviously wrong answers first. Common traps: confusing live/neutral/earth.
- •Paper 4: Use KEYWORDS: "isolate", "large current", "melts", "low resistance path".
- •Paper 6: Always calculate current (I = P/V) before choosing a fuse. Choose next rating ABOVE.
⚡ THE ULTIMATE EXAMINER'S TRAP
Students LOSE MARKS by saying "the fuse stops too much current" (WRONG). The correct answer: "Excess current causes the fuse wire to MELT, which BREAKS the circuit and disconnects the appliance from the supply." Always explain the MECHANISM, not just the outcome!
