A) high R low L
B) high R high L
C) low R high L
D) high R low C
Correct Answer: C
Solution :
Power consumption \[={{I}_{rms\,}}{{V}_{rms}}\cos \phi \] Where \[\cos \phi \] is power factor, \[\cos \phi =\frac{R}{Z}\] for \[\phi \] to be minimum, R should be minimum and Z should be higher. So higher Z (impedence) L (inductance) should be high.You need to login to perform this action.
