The Rule is that the sum of currents on *all* the box's conductors has to add to zero. If the box has only two terminals, the sum of the two has to be zero -- the only way to get around that would be to put Cecil into the box and have him suck coulombs just as fast as he can. If that two-terminal box contains an inductor, then the current out has to equal the current in -- that's the only way the sum of currents at the two terminals can sum to zero. That's just the point, Roy. The two terminals don't have to sum to zero for a distributed network problem, like 1/2WL of coax coiled up inside that black box. But one thing you can take to the bank, folks: the sum of the currents on all the terminals better add to zero. Unless, of course, Cecil is in the box. Are you saying I cannot coil up 1/2WL of coax inside a black box and observe current flowing into both terminals for 1/2 cycle and current flowing out of both terminals for 1/2 cycle? That would be quite a revelation. -- 73, Cecil http://www.qsl.net/w5dxp -----= Posted via Newsfeeds.Com, Uncensored Usenet News =----- http://www.newsfeeds.com - The #1 Newsgroup Service in the World! -----== Over 100,000 Newsgroups - 19 Different Servers! =----- |

You also need to go back and read the fourth sentence of my posting.
