51.	The transform impedance of the capacitor is?(a) C(b) 1/C(c) sC(d) 1/sCI got this question in an internship interview.My doubt stems from The Concept of Complex Frequency in division S-Domain Analysis of Network Theory
Answer» Correct OPTION is (d) 1/sC The best I can explain: The transform impedance of the capacitor is the ratio of the transform VOLTAGE V1(s) to the transform CURRENT IC(s) and is ZC(s) = 1/Cs.

52.	The transform admittance of the capacitor is?(a) 1/sC(b) sC(c) 1/C(d) CThis question was posed to me in an interview for job.This intriguing question comes from The Concept of Complex Frequency in portion S-Domain Analysis of Network Theory
Answer» Correct option is (b) sC The explanation: The transform ADMITTANCE of the capacitor is the ratio of transform CURRENT I1(s) to transform VOLTAGE VC(s) and is YC(s) = sC.

53.	The equivalent transform circuit contains an admittance of value ____ and equivalent transform current source.(a) 1/L(b) 1/sL(c) L(d) sLThe question was posed to me in unit test.This intriguing question comes from The Concept of Complex Frequency topic in section S-Domain Analysis of Network Theory
Answer» RIGHT ANSWER is (b) 1/sL Easy explanation: The time domain REPRESENTATION of inductor L has initial current iL(0^+). The equivalent transform circuit contains an admittance of VALUE 1/sL and equivalent transform current source.

54.	The ratio of transform voltage to the transform current is defined as _________ of the resistor.(a) transform voltage(b) transform current(c) transform impedance(d) transform admittanceThe question was asked in semester exam.I'd like to ask this question from The Concept of Complex Frequency in portion S-Domain Analysis of Network Theory
Answer» Right choice is (c) transform impedance To explain I would say: Transform impedance of the RESISTOR is defined as the ratio of transform VOLTAGE to the transform CURRENT and is expressed as ZR(s) = VR(s)/IR(s) = R.

55.	The transform admittance of the inductor is?(a) 1/sL(b) sL(c) 1/L(d) LI had been asked this question in semester exam.I need to ask this question from The Concept of Complex Frequency topic in division S-Domain Analysis of Network Theory
Answer» RIGHT OPTION is (a) 1/sL The best I can explain: The transform admittance of the INDUCTOR is YL(s) = I1(s)/VL(s) = 1/sL where I1(s) is the TOTAL transform current through the inductor L.

56.	The transform impedance of the inductor is?(a) L(b) 1/L(c) sL(d) 1/sLThe question was asked during an internship interview.The question is from The Concept of Complex Frequency topic in portion S-Domain Analysis of Network Theory
Answer» The correct option is (c) SL Explanation: CONSIDERING the sum of the transform VOLTAGE and the initial current voltage as V1(s) we have the transform impedance of the inductor. The transform impedance of the inductor is ZL(s) = V1(s)/IL(s) = sL.

57.	The ratio of transform current to the transform voltage is defined as ________ of the resistor.(a) transform admittance(b) transform impedance(c) transform current(d) transform voltageI had been asked this question at a job interview.This key question is from The Concept of Complex Frequency topic in division S-Domain Analysis of Network Theory
Answer» Right choice is (a) transform ADMITTANCE Best explanation: Transform admittance of the RESISTOR is defined as the RATIO of transform current to the transform VOLTAGE and it is also defined as the reciprocal of transform IMPEDANCE. YR(s) = IR(s)/VR(s) = G.
