Question 10

Cos –¹ 0.8 = 36.8699 calculation details 

Ic=50 ampere 0.707 cos phy 

Details of  0.707 cos phy= 50 angle -45 , 

details of Ic = 50 ampere - 45 degree = 35.355 - j 35.3553 ampere 

Id = 30 ampere 0.8 Cos phy , = cos 0.8 value details above , = Id = 30 angle - 36.869 degree , 

Id = 30 angle - 36.869 degree = 24 - j 18 ampere , 

=
