| RELATIONSHIPS AND LAWS - BASIC FORMULAS | ||
Up to this point, four of the most important electrical quantities have been discussed. These are voltage (E), current (I), power (P), and resistance (R). The relationships that exist among these quantities is critical because they are used throughout the study of electricity. Previously, P was expressed in terms of the other three basic quantities E, I, and R. In practice, any one of these quantities can be expressed in terms of any two of the others. Shown is a summary of these 12 basic formulas. |
