The zeros of driving point impedance are those frequencies corresponding to ___________ conditions.(a) current source(b) open circuit(c) voltage source(d) short circuitThe question was posed to me in a national level competition.Origin of the question is Properties of Driving Point Functions in division S-Domain Analysis of Network Theory

Answer»

Right ANSWER is (d) SHORT CIRCUIT

Explanation: The zeros of driving point impedance are those FREQUENCIES corresponding to short circuit CONDITIONS as a pole of Z(s) is a zero of I(s) and zero of N(s) is a zero of V(s), it signifies a short circuit.
