 Peng_Li Junior Member  Offline Posts: 10 Hangzhou, China Power calculation when a high-frequency sinusoidal voltage source is applied Oct 4th, 2019, 8:20pm   Hi, In my recent work, I need to calculate the electrical power consumed by a conductor (using Verilog-A). As we know, the impedance of a conductor varies with the frequency of the electrical excitation applied. For example, its dc resistance is assumed to be Rdc, and the resistance at 20 GHz is assumed to be Rac (because of skin effect).The electrical excitation is a sinusoidal voltage source, which is expressed asV=V0+Va*sin(2*pi*freq*t)where V0 is the dc component; Va is the amplitude of the ac component; freq is the frequency; t is the time.My question is, in the following, which is the correct way to calculate the electrical power consumption of the conductor?(1) Power consumption on Rac with both dc and ac voltage component applied(2) The summation of dc power consumption on Rdc and ac power consumption on RacAny help would be greatly appreciated, thank you.
