| Combination will be L=(25*50/75)+20=36.6 XL=2*Pi*f*L=2*3.14*300*1000*36.6*(1/1000000 )=68(approx) current=V/XL=60/68=.87=870mA |

| Input=output + losses. =4*10^3 + 800. |

| 1. L1 parallel with L2, which is ( 25 micro * 50 micro)/( 25 micro + 50 micro) = 16.67 micro Henry. 2. L1 and L2 parallel value series with L3 which is ( 16.67 Micro + 20 Micro) = 36.67 micro Henry. So now put into the formula, I rms= Vrms / 2*pai *F*L. = 60/( 2*pi*300K*36.67 micro). =0.87 A. = 870 mA. |
