Electrical Formulas - engineeringtoolbox

Power is consumption of energy by consumption of time. Example - Energy lost in a Resistor. A 12 V battery is connected in series with a resistance of 50 ohm. The power consumed in the resistor can be calculated as. P = (12 V) 2 / (50 ohm) = 2.9 W. The energy dissipated in 60 seconds can be calculated.

5 Steps for Calculating Sample Size - The Analysis Factor

Step 5. Specify the intended power of the test. The power of a test is the probability of finding significance if the alternative hypothesis is true. A power of .8 is the minimum. If it will be difficult to rerun the study or add a few more participants, a power of .9 is better. If you are applying for a grant, a power of .9 is always better.
