1. The magnetic circuit for a saturable reactor is shown in Fig. P1 below. The B-H curve for the core material can be approximated as two straight lines as shown. (a) If I-2.04, calculate the value of 12 required to produce a flux-density of 0.67 in the vertical limbs. (b) If I=0.5A and 12-1.964, calculate the total flux in the core. Neglect magnetic leakage.
