The lessons in order
| Ref | Lesson pack | Structure | Worksheet | Quiz | Lab tab |
|---|---|---|---|---|---|
| 19.1 | Capacitors and capacitance Capacitance is a single ratio, charge per volt, but combining capacitors flips the rules you learned for resistors. | Cooperative Concept Mapping | 6 Q, 67 marks (topic) | 4 checks | tab 1 |
| 19.2 | Energy stored in a capacitor Charging a capacitor does work against the charge already there, and that work is stored as energy. | Think-Pair-Share | 5 Q, 57 marks (topic) | 4 checks | tab 2 |
| 19.3 | Discharging a capacitor Let a charged capacitor empty through a resistor and the charge does not fall steadily: it decays exponentially, fast at first and ever more slowly, set by a single time constant. | Mix-Pair-Share | 3 Q, 35 marks (topic) | 4 checks | tab 3 |
Each pack holds the plan, worksheet and quiz for its lesson. Teach the rows in order; the lab tabs match the student lessons.
