Given below are two statements, one is labelled as Assertion (A) and the other is labelled as Reason (R):
Assertion (A): In an impedance, Smith chart point r =0, x=0 represents open-circuit point.
Reason (R): In an impedance, Smith chart, √r = -1 and √i = 0 represents r = 0 and x = 0.
In the light of the above statements, choose the correct answer from the options given below.
Assertion (A): In an impedance, Smith chart point r =0, x=0 represents open-circuit point.
Reason (R): In an impedance, Smith chart, √r = -1 and √i = 0 represents r = 0 and x = 0.
In the light of the above statements, choose the correct answer from the options given below.
1
Both (A) and (R) are true and (R) is the correct explanation of (A)
2
Both (A) and (R) are true but (R) is not the correct explanation of (A)
3
(A) is true but (R) is false
4
(A) is false but (R) is true
