1.	The capacitance per unit length and the characteristic impedance of a lossless transmission line are C and Z respectively. The velocity of a travelling wave on the transmission line is(a) ZC(b) 1/ZC(c) Z/C(d) C/ZThe question was asked during an online interview.This key question is from Advanced and Tricky Questions in portion Advanced and Tricky Questions of Electromagnetic Theory
Answer» Right CHOICE is (b) 1/ZC Easy explanation: The characteristic impedance of the Z = √(L/C) and the VELOCITY of propagation is V = 1/√(LC). THUS we get V = 1/ZC.
