Answer 1

Now, And- In the equivalent magnetic Ciar cunt, Fi-N, I, -500x10 = 5000 Ait F2 = N2I2= 500x 10 = 5000 At Mc = 1150 Mo = 1150 x 45 x 10-7 Roate = loafe - 3×52x10-2 MC AC 1150 x 4 x 10-7x4x10-4 Roate = 2:69X106 At/wo From Symmetors . Rocde = Reate da - Slo-3 Mo Ag 47x10-7x2x2x1024 Rg=9.94 x 106 AdWS - lbeccone) ___ 51.5*10-2 Mc Ac 1150x4 TTX10-7x4x10-4 Roelcare) = 0.89*106 At/wo The loop equations are Bic Roate t Ryet Rg) +$2(Ribe tRg)= F. Bic Robet Rg) +$2C Rocket Roe t Rg)= F2 ooi (13:52x106) + 02 (10.83%100) =5000 Pi (10.83x106) +$2 (13.52 X106) = 5000 @ Rg Mony Kbel (091)
