if the impedance of a system is 4 ohm, calculate its admittance.(a) 0.

1.	if the impedance of a system is 4 ohm, calculate its admittance.(a) 0.25 ohm^-1(b) 4 ohm^-1(c) 25 ohm^-1(d) 0.4 ohm^-1I had been asked this question in homework.This interesting question is from Basic AC Parallel Circuits topic in chapter Single-Phase Parallel Networks of Basic Electrical Engineering
Answer» CORRECT choice is (a) 0.25 ohm^-1 For EXPLANATION: We KNOW that: Y=1/Z. Substituting the value of Z from the question, we get Y = 1/4 = 0.25 => Y= 0.25 ohm^-1.
