Since typed formulas are dificult to read I will be putting together a collection formula images here as I make them. They will all have transparent backgrounds Here's the first. This is the parallel resistance formula.

| Scott Vickrey |  Here's the ohms law formula in it's pyramid form. This format helps people visualize how the formula can be flipped around to solve for any of it's components. E = I x R or I = E / R or R = E / I To use this image on any site: Use the following address. http://www.electricalknowledge.com/images/OhmsLawPyramid.gif Requirements for use: Include a link to http://www.electricalknowledge.com/default.asp?CAT_ID=6 Try to state that this is a link to EK's Images and Drawings collection.

| JimmyDee | quote: Notice that the letters that represent the three unknowns are in alphabetical order. To solve for any unknown, cover that and your formula is the remaining two exactly as written. The power formula triangle is arranged in reverse alphabetical order. Easy for me to remember that way. Jim |
| komaraiah | thak you so much i didnt understand the specific resistance of the cables how to find out plz tell me |
