A Level Physics - An Overview on Current of Electricity and DC Circuits
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
