Ohm's Law Formula Card for AC and DC
We are offering these half sheets at 25 cents each. Here's a convenient Ohms law formula chart to carry with you in your glove box or folder, which shows series circuit formulas, parallel circuit formulas, for both AC and DC theory formulas for impedance and resistance.
These handy electrical formulas and electronics formulas (AC Ohm's law formulas on front, DC Ohm's law formulas on back) also give you very useful formulas for apparent power, 3-phase apparent power, power factor, reactance, motor sync. generator frequency, 3-phase WYE, 3-phase delta, sine wave values and more! Image will be clearer than shown - Sized at approximately 8.5" x 6". This chart is copyright of TNT, so no reprinting, please.
As you can see on the Ohm's law charts, there's a wide variety of colors encircling the diagram. These colors serve a purpose. You can easily identify resistor band colors by looking at the chart. For instance the color brown in the 1:00 position represents the value of one...and so forth, up to the silver in the 10 minutes to position which represents 10% tolerance - the gold in the 5 minutes to position represents 5% tolerance.

FEEDBACK ON THIS PRODUCT:
Anne and her Technotetime Co. , have made a wonderful laminated "OHM” Law formula chart " for AC, DC, Series, Parallel, and Resistors Color Coding that are perfect for all electrical students. I give them to the four levels of Electrical Apprentices, Motor Control Classes, National Electrical Code classes, and the Fire Alarm classes that we teach. The students , no matter their age or experience , believe and say they are a great learning tool. They also work as a book mark for the National Electrical Code. It is a cool idea that is functional and helps the students learn and have access to all the pertinent information needed." J. Outland, M.C. Dean,Inc. Dulles, VA
"The students loved the Ohms Law cards---even students who have been in
the field learned more by using your card. Thank you again." Steven Wilson, American River College
