  • Current, potential difference, and resistance: Ohm's Law, resistivity, and the use of circuit diagrams.
  • Capacitors: Capacitance, charging and discharging of capacitors, and energy stored in a capacitor.

Understanding Question Types and Strategies

AQA A-Level Physics Paper 1 employs a variety of question types, each requiring a specific approach:

• Multiple-choice questions: These assess your understanding of fundamental concepts. Read each question carefully, eliminate obviously incorrect answers, and consider the underlying physics principles. Don't be afraid to make an educated guess if you are unsure.

• Short-answer questions: These demand concise, well-structured answers. Clearly define key terms, use appropriate units, and show your working for calculations. Focus on providing relevant information and avoid unnecessary details.

• Longer-answer questions: These require a more in-depth understanding and the ability to apply your knowledge to solve complex problems. Break down the question into smaller parts, clearly state your assumptions, show your working step-by-step, and provide thorough explanations. Always include units in your answers and check for any significant figures errors.
