Electrical Engg (EEE) - MCQ Practice Questions

Both nodal and mesh analysis can handle dependent sources. The choice depends on circuit configuration - nodal for current sources, mesh for voltage sources.

RTh is calculated by replacing independent voltage sources with short circuits and independent current sources with open circuits, while keeping dependent sources intact.

Reciprocity theorem applies to linear passive networks without dependent sources. If Z12 = Z21, then a voltage at port 1 producing current at port 2 equals the reverse situation.

KCL is based on charge conservation and applies at ALL times - steady state and transients both. It's independent of whether sources are constant or time-varying.

H21 = I2/I1 (with V2=0) is the current transfer ratio or short-circuit current gain in a two-port network using hybrid parameters.

XL = 2πfL = 2π(50)(5) = 500π ≈ 1570.8Ω. For pure inductor, impedance is purely reactive with magnitude 1570.8Ω.
