(D) Becomes zero
(D) Becomes zero
Ans: (B) Decreases
Explanation:
tan Ï• = XL/R and Power factor=cos Ï•
As XL increases, tan Ï• increases, Ï• increases, cos Ï• decreases and hence power factor decreases.
As XL increases, tan Ï• increases, Ï• increases, cos Ï• decreases and hence power factor decreases.
