AQA A-level Physics Electronics lesson on MOSFETs as switches. 21 editable slides, 28-mark worksheet, mark scheme and PDFs.
What’s in the PowerPoint
• A circuits recap starter, with answers in the speaker notes
• The structure of an N-channel enhancement MOSFET, with an original cross-section diagram
• The symbol, VGS, VDS, IDSS and Vth, and the characteristic graph
• Why the gate draws no current, and switching a load
• The gate resistor and the protection diode
• Three worked examples: on or off, the switching point, and the power in the MOSFET
• A practical: a dark-activated switch
• A common mistakes slide based on AQA examiner reports
• Six check questions with answers, and an exit ticket
• Teacher notes on every slide: spec references, examiner report tips, prior knowledge pages and practical ideas
What’s in the worksheet (28 marks)
• Recall of the structure, Vth, IDSS and why the input resistance matters
• Reading a MOSFET characteristic graph
• Potential divider switching and power calculations
• A 5-mark circuit question with a gate resistor and protection diode
• A full mark scheme with mark points, on separate pages
• PDF copies of the slides, the student worksheet (no answers) and the mark scheme, ready to print
Good for: first teaching, revision, homework, cover lessons or independent study. The PowerPoint and Word files are fully editable, and the PDFs are ready to print or share with students.
