How to Evaluate Average Power?

Average Power evaluator uses Average Power = 1/2*Sinusoidal Current^2*Radiation Resistance to evaluate the Average Power, Average Power is the total energy transferred over a period of time divided by that time duration, representing the constant power level that delivers the same energy. Average Power is denoted by P_r symbol.

How to evaluate Average Power using this online evaluator? To use this online evaluator for Average Power, enter Sinusoidal Current (i_o) & Radiation Resistance (R_rad) and hit the calculate button.

FAQs on Average Power
