CEGEP Electricity & Magnetism Tutoring
Make sense of charge, fields, potential and circuits in CEGEP physics. Connect vector reasoning with circuit relationships and induction rather than memorizing disconnected equations.
Topics covered
Common difficulties
- Adding potentials as scalars but fields as vectors
- Recognizing series and parallel connections after a circuit is redrawn
- Determining an induced-current direction from changing flux
How tutoring can help
Start with the quantity being requested: force, field, voltage, current or energy. We use unit checks and sketches to keep those distinct. Circuits are redrawn by connections, not by appearance. For induction, predict the response to the flux change before calculating its magnitude.
Current codes and earlier search terms
These are subject crosswalks for the Science program, not transfer-credit decisions. The prefix matters: 201-SN1 is probability and statistics, while 203-SN1 is mechanics. Local codes and scope vary; your current outline is the reference.
| Subject | Current code | Earlier term |
|---|---|---|
| Electricity and magnetism | 203-SN2-RE | 203-NYB-05 |

An example that connects the ideas
Two 6 Ω resistors in series have resistance 12 Ω. Across 12 V, the current is 1 A through each. In parallel, their equivalent resistance is 3 Ω and the total current is 4 A, splitting into 2 A per branch. Connections, not the drawing’s shape, determine the model.
A question to check understanding
What stays equal in parallel: current or potential difference? Potential difference. Equal branch currents here result from the equal resistances.

Review with a clear plan.
Use mixed problems that require a principle choice, then justify direction and sign before arithmetic. Practise junction and loop equations together, checking whether calculated currents satisfy charge conservation. Confirm the section’s circuit and induction scope with the outline.
