A level physics: Electrical power formula work questions and answers

This resource includes:

• Double-sided A4 sheet of questions on electrical power P = VI = I^2R = V^2/R.
• Separate word document containing the questions and worked solutions.
• Powerpoint show (2 slides) containing the answers only.

It assumes students have already done some work on internal resistance, but it probably won’t matter too much (except for the final, extension question) if they haven’t.

Includes a recap of choosing correct fuse to use with certain P and V.
