Question

Need help solving problem 4

Consider the magnetic circuit below. All 3 coils have equal turns N- 20. Assume the core is linear with a permeability of p 5x10 H/m, average length i- 2x 10* m, cross section area A- 1 x 10 m2 Ignore the core losses and copper winding resistance. The current flowing though the top coll is sinusoidal with an ms value of 10 A and frequency of 60 Hz) Determine the following: 1) Reluctance of the core-ㄑㄧ-t-b。 a), x 10 Amp.turnwb w: STI,ให้ b 2 x 10 Amp.turn/Wh 3 x 10.
