| Lesson Topic: Define electric current as the charge passing a point per unit time; recall and use the equation I = Q / t |
Learning Objective/s:
- Define electric current as the rate of charge flow.
- Apply I = Q/t to calculate current, charge, or time.
- Distinguish between charge and current and use correct SI units.
- Solve quick‑check problems involving I, Q, and t.
- Explain common misconceptions about direction and scalar nature of current.
|
Materials Needed:
- Projector and screen
- Whiteboard and markers
- Printed worksheet with practice questions
- Scientific calculators
- Simple circuit diagram handout
- PowerPoint slides summarising definition and equation
|
Introduction:
Begin with a quick demonstration of a flashlight turning on as a battery supplies charge, asking students what they think is moving. Recall that they have already studied charge (coulombs) and basic unit conversion. State that by the end of the lesson they will be able to calculate current using I = Q/t and interpret its meaning.
|
Lesson Structure:
- Do‑now (5'): Students write a definition of electric current and list its unit.
- Teacher input (10'): Present the definition, symbol I, SI unit ampere, and the equation I = Q/t.
- Guided practice (12'): Work through the example 12 C in 3 s, students calculate I = 4 A.
- Misconception check (8'): Discuss common errors (current ≠ charge, direction of conventional current, scalar nature) using true/false statements.
- Independent practice (10'): Students solve the three quick‑check questions on their worksheet.
- Summary & exit ticket (5'): Each student writes one correct statement about current and one misconception they corrected; collect for assessment.
|
Conclusion:
Recap that electric current is the rate of charge flow and that I = Q/t links the three quantities. Collect exit tickets as a retrieval check and assign homework to complete additional I = Q/t problems from the textbook.
