A comprehensive lesson which teaches students about Ohm’s law and how IV graphs are sketched for fixed resistors, diodes, thermistors, LDRs and filament bulbs. This lesson was designed to fit needs of the AQA a-level physics course - unit 5 electricity.
Tasks are differentiated to suit the needs of each learner.
Learning objective: To investigate the relationship between current and voltage in different circuit components.
By the end of the lesson learners should be able to:
Success criteria:
I can describe the IV graph trends for filament bulbs, diodes, fixed resistors, thermistors and LDRs
I can apply Ohm’s law to identify and then justify why IV graphs might be different.
I can apply my knowledge to answer past paper questions.
Powerpoint contains 30 slides.
Contains past paper questions that target this topic, some questions require knowledge from prior lessons.
