Answer 1

For a parallel plate transmission line, let v be the speed of propagation and Z be the characteristic impedance. Neglecting fringe effects, a reduction of the spacing between the plates by a factor of two results in

(A) halving of v and no change in Z

(B) no changes in v and halving of Z

(C) no change in both v and Z

(D) halving of both v and Z

Correct answer (B) no changes in .
