(b) A transformer takes a current of 0.7A, when its primary is connected to a 225V, 50Hz supply, the secondary being open circuited. If the power absorbed is 70watts, determine (i) the core loss current(Ic) (ii) the power factor on no-load and (iii) the magnetizing current(Im) (3)core loss current(Ic)? (2)power factor? (3)Magnetizing current (Im)?
