IGCSE Physics: Charge and Q = It | Edexcel Modular | Unit 2 | L2

IGCSE Physics: Charge and Q = It | Edexcel Modular | Unit 2 | L2

This lesson covers spec points 2.14, 2.15 and 2.16 — knowing that current is
the rate of flow of charge, using Q = It to calculate charge, current and time,
and understanding that current in a solid metal conductor is a flow of
negatively charged electrons.

PowerPoint includes:
• Retrieval starter reviewing circuit symbols and current from L1
• Direct Instruction (I Do) — charge defined and linked to current; Q = It
introduced in words and symbols; each variable defined with units; worked
examples calculating charge, current and time; electron flow explained and
distinguished from conventional current direction
• Guided Practice (We Do) — three calculations: find charge from current and
time; find current from charge and time; find time for a given charge to flow
• Independent Practice (You Do) — Q = It calculations in real-world contexts;
rearrangement tasks; explain why current in a metal wire is a flow of
electrons, not protons
• Review and Reflect — 3 MCQs and exit ticket

Activity Sheet includes:
• Formula box: Q = It
• 10 exam-style questions covering charge calculations, all three
rearrangements, and electron flow explanations
• Stretch question combining Q = It with E = QV to find energy transferred
• Full mark scheme for teacher use
