Electric Fields and Capacitance Problem Solving Mastery

A set of 30 exam-style questions covering the electric fields and capacitance content of A-level Physics, with full mark schemes, worked solutions and teacher notes. Written to match the AQA A-level Physics specification (7408), and suitable for other exam boards’ electric fields and capacitance content too.

What’s included

• 30 multi-part exam-style questions, increasing in difficulty
• Full mark schemes for every question
• Fully worked solutions with clear, structured steps
• Teacher notes highlighting key ideas and common misconceptions

Content coverage

• Coulomb’s law, including resultant forces and comparison with gravity for subatomic particles
• Electric field strength in uniform and radial fields, and field lines
• Deflection of charged particles in a uniform field
• Mapping fields and equipotentials with conducting paper
• Electric potential, work done moving a charge, and equipotentials
• Graphs of field strength and potential against distance: gradients and areas
• Closest approach of an alpha particle to a nucleus
• Similarities and differences between gravitational and electric fields
• Capacitance, parallel-plate capacitors, permittivity and dielectrics
• Energy stored by a capacitor, from the charge–pd graph
• Charging and discharging through a resistor: exponential graphs, time constant and half-life
• Required practical: charging and discharging a capacitor, including log-linear graphs
• Real-world applications, including a defibrillator
• Mixed multi-step exam-style problems

Who is it for?

• A-level Physics students in Year 13, and anyone revising for their final exams
• Teachers looking for ready-to-use exam practice
• Homework, independent study, revision or assessment

Why use it?

• Written by an experienced Head of Physics to match the style and difficulty of real exam questions
• Required practical covered in exam-style questions, including graph analysis and uncertainty
• Gives plenty of practice at the parts of capacitor discharge students find hardest: finding the time constant from a log-linear graph, and remembering that energy depends on the square of the pd
• Builds confidence from standard questions up to more challenging ones
• Saves time on lesson planning and resource creation

Format: PDF, suitable for printing or digital use.
