Physics Electric Circuits and Materials

A comprehensive Edexcel AS/A Level Physics Electric Circuits and Materials revision PowerPoint designed for classroom teaching, intervention, retrieval practice and exam preparation.

Each topic begins with Do Now (DNA) retrieval questions followed by a separate answer slide for immediate feedback and correction. Key knowledge is presented using a Cornell note-taking structure with Cues/Questions, Main Notes and Summary sections to support organised revision and long-term retention.

After each key point, students complete three short-answer whiteboard questions testing knowledge, understanding and common misconceptions. Answers are provided for rapid assessment and correction. Longer book-work questions are followed by clear answer notes.

Topics include:
• Current, charge, potential difference and resistance
• Electrical energy, power and EMF
• Current–voltage characteristics
• Ohmic conductors, filament lamps and diodes
• Thermistors and temperature effects
• Resistivity, drift velocity and charge carriers
• Superconductivity and applications
• Series and parallel circuits
• Cells in series and parallel
• Kirchhoff-style current and p.d. reasoning
• Electrical heating and power loss
• Potential dividers, LDRs and thermistors
• Internal resistance and lost volts
• Density and upthrust
• Stokes’ law
• Hooke’s law, elastic strain energy and springs
• Stress, strain, Young modulus, ductile and brittle materials

Designed for board display with organised layouts, large readable text, visuals, misconception checks and exam-focused practice.
