I haven't taketaken a course on TLtransmission lines or RF so barebear with me.
Using EM we can calculate the capacitance and inductance of traces. I'm somewhat confused on the value of this calculation, though, because the telegraphers equation basically says you can't consider the trace as a lumped element.
Could someone explain underUnder what circumstances you can you use the trace capacitance as a replacement for a lumped element? What is the value of these calculations and where can you use them?
