Teach resistance of a wire and resistor combinations with this AQA GCSE Physics Required Practical 3 workbook, including answers, printable PDFs and editable Word files.

Designed for AQA GCSE Physics 8463, this 43-page resource takes students through practical planning, circuit setup, measurements, calculations, graph interpretation and evaluation.

WHAT YOU RECEIVE

• Student workbook: 27 pages.
• Separate teacher guide with answers and marking guidance: 16 pages.
• Both documents supplied as PDF and editable Word files.
• 80 questions and practical tasks.
• 9 worked examples.
• An original 30-mark assessment, including a six-mark practical-method question.

TOPICS AND SKILLS COVERED

• Investigating how wire length affects resistance at constant temperature.
• Comparing individual resistors with series and parallel combinations.
• Reading circuit diagrams and connecting ammeters and voltmeters correctly.
• Conventional current direction and branch-current rules.
• Calculating resistance using R = V/I and converting milliamperes to amperes.
• Measuring contact positions and converting wire length into metres.
• Recording raw measurements, processing repeats and calculating means.
• Plotting resistance against length, drawing a line of best fit and calculating gradients.
• Distinguishing direct proportionality from a graph with a non-zero intercept.
• Identifying anomalies, evaluating limitations and suggesting improvements.

TEACHER SUPPORT

• Answers with student-page references.
• Apparatus and safety guidance.
• Assessment mark scheme and a model six-mark response.
• Graph-reading tolerances and common misconceptions.

Suitable for KS4, Years 10–11, practical preparation, follow-up lessons, homework, revision and targeted intervention.

Word text, tables and equations are editable. Diagrams and graphs are embedded images.

An optional extension page explains the parallel reciprocal-resistance formula and is clearly labelled beyond the required AQA 8463 calculation scope.
