Hi, In my recent work, I need to calculate the electrical power consumed by a conductor (using VerilogA).
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 R_{dc}, and the resistance at 20 GHz is assumed to be R_{ac} (because of skin effect). The electrical excitation is a sinusoidal voltage source, which is expressed as V=V_{0}+V_{a}*sin(2*pi*freq*t) where V_{0} is the dc component; V_{a} 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 R_{ac} with both dc and ac voltage component applied (2) The summation of dc power consumption on R_{dc} and ac power consumption on R_{ac}
Any help would be greatly appreciated, thank you.
