This resource is a complete teaching presentation that explains the principles of capacitors, their behaviour in circuits, and their applications. It blends theory, worked examples, and practice questions, making it suitable for both classroom delivery and independent study.

The resource includes:

  • Definition of capacitance and the relationship between charge, potential difference, and capacitance.
  • Types of capacitors - parallel plate, spherical, cylindrical, and their practical uses.
  • Factors affecting capacitance - plate area, separation, and the role of dielectrics.
  • Capacitors in series and parallel - derivations and worked examples.
  • Energy stored in a capacitor - equations, energy–voltage graphs, and practical contexts.
  • Charging and discharging - current and voltage variation, exponential decay, and equations.
  • Time constant (τ = RC) - its meaning, applications, and effect on charge/discharge rate.
  • Exam-style questions and problem-solving exercises to consolidate learning.

This resource can be used by teachers as a lesson presentation, revision tool, or problem-solving aid, while students can use it for self-study and exam preparation.
