I think I have something of interest to Mike Holt. In your "Basic Electrical Theory" 3rd. edition on page 100 you introduce Ohm's Law Formula Circle and on page 102 you show the Power Formula Circle. Here are two more Formula Circles which will complete this form of equation solution system. (1). P= I2 R (2). E2=P R The first formula is the Heat Loss formula. You need only to square I at the start or at the end take the square root. When the four circles are used together all 12 formulas of the expanded power wheel are covered. Now we have only 4 Formulas to remember instead of 12. P.S. I like to call the last formula "Leo's Law"
