A comprehensive lesson which teaches students about how IV graphs appear for fixed resistors, filament bulbs and diodes. The lesson also delves into the reasoning behind why these trends arise.
Progress checks are available following each success criteria
Tasks are differentiated to suit the needs of each learner.
Learning objective: Use Ohm’s law to justify the trends seen in IV graphs for a fixed resistor, filament bulb and LED.
By the end of the lesson learners should be able to:
Success criteria:
-Identify generally what happens to current as voltage increases.
-Describe how to calculate resistance from a voltage-current graph.
-Compare how the resistance changes with load in: fixed resistors, filament bulbs and diodes.
Powerpoint contains 22 slides and a collection of past paper questions including the marking scheme.
