Electrical Circuits & Machines — Solved Papers

Every paper: nodal/mesh with dependent sources + matrix; IC at 0+; classical RLC; Laplace switched circuit; Bode asymptotes; two-port Z/ABCD/h; machines short notes.
Numeric care: generator Ia=IL+Ish, motor Ia=IL−If; Pcu∝x²; fr=s f; Φm≈V/(4.44 f N).
IC recipe: 0− steady (L short, C open) → continuity iL,vC → 0+ equivalents (L open-ish for di/dt from vL=L di/dt; C short-ish for vC) → derivatives from differentiated KCL/KVL.
Bode: factor, cancel, write as K·∏(1+s/z)/∏(1+s/p), list corners, walk slopes ±20 (±40 quadratic).
