Default Standing-Wave Current vs Traveling-Wave Current

v(t, x) = vf(t, x) + vr(t, x) = Vs * sin(wt) * cos(x)

This clearly shows that the total voltage at any point along the line is
sinusoidal and in phase at all points.


It also clearly implies that statement is true for current
as well.

SOMEONE PLEASE PASS THIS CHALLENGE ON TO ROY. HE HAS
DUCKED AND DODGED AND REFUSED TO ANSWER FOR MUCH TOO LONG.
ONE OF HIS PLOYS IS TO SAY HE NEVER SAW THE CHALLENGE
BECAUSE HE HAS PLOINKED ME.

EXACTLY HOW CAN A CURRENT WHICH YOU ADMIT IS IN PHASE AT
ALL POINTS BE USED TO MEASURE THE DELAY THROUGH A 75M
BUGCATCHER LOADING COIL?

It's pretty obvious from experience that Roy would rather
mount an ad hominem attack against me rather than answer
the simple question above.
