💡 Exam Tips for Potential Difference

🎯 Common Question Types:

  • Calculate energy transferred: E = VQ (2 marks)
  • Find missing voltage in a series circuit (2 marks)
  • State voltage across parallel branches (1 mark)
  • Explain voltmeter connection method (2 marks)
  • Describe the difference between EMF and p.d. (2 marks)

📝 Key Command Words:

  • State — give a brief factual answer, no explanation needed
  • Explain — use "because" to give a reason
  • Calculate — show the substitution and units
  • Compare — identify similarities AND differences

⚠️ Common Mistakes to Avoid:

  • Connecting a voltmeter in series — it must be in parallel
  • Forgetting that parallel branches ALL have the same voltage
  • Confusing EMF (supply) with p.d. (across a component)
  • Forgetting units: energy in J, charge in C, voltage in V
  • Using E = Pt instead of E = VQ when charge is given

Quick Check: How should a voltmeter be connected in a circuit, and why?

P.d. equation?
V = E/Q where V = voltage (V), E = energy (J), Q = charge (C). Also V = IR.
What is 1 Volt?
1 Joule per Coulomb (1 V = 1 J/C)
