Hello,
I've been reading through the first few sections of this website on transmission lines and just wanted to clarify something.
I'm doing an assignment where I'm hooking up an infinite length of RG-58/U coax cable to the output of a logic gate. basically i just want to work out the current that flows into the cable so I'm thinking i'll need to know the voltage at the end of the infinite length of cable (nothing is hooked up to it at the end).
So is the voltage at the end 0 V, because there is inductance in the transmission line causing voltage drops... ?
I'm a little confused as I was reading some info that made it sound like the voltage at the end of the line would be the same as voltage at the beginning of the transmission line. I wouldn't think this would be very useful though, as then the current through the line would be nearly 0.
Thanks.
