Almost all the essential concepts for A Level Physics Electrical topics can be found in this video. These concepts can be drawn in a form of cheat sheet or mindmap as I have demonstrated in the video. Doing so can help students to remember better.
Concepts covered in the video:
- Definition of Current
- Formula of current including its form in calculus
- Definition of potential difference and emf (electromotive force)
- Formula of potential difference and emf
- Difference between potential difference and emf
- Batteries with internal resistance
- Terminal Potential Difference and related graphs
- Definition of resistance
- Effective resistance of resistors in series and parallel circuits
- Potential Divider Rule formula
- How to apply potential divider rule
- Ohm’s Law
- Ohmic and non-ohmic conductors
