Paper pattern
- Section A: Attempt all questions. (14 marks)
- Section B: Attempt any THREE questions out of five. (21 marks)
- Section C: Attempt ONE question from each pair (a or b). (35 marks)
Why these questions
- Unit 1 (DC Circuits) dominates — 23% avg weightage
- Asked every year: Circuit Elements and Sources, Kirchhoff's Laws
- Low priority (never asked): Magnetic Circuits
- Most repeated topic: Mesh and Nodal Analysis
Section A – 2-mark questions
- Describe the following elements briefly: (i) Independent Ideal Voltage source (ii) Independent Ideal Current source
- Why the average power consumed in purely inductive circuit is zero?
- Draw the phasor diagram for an ideal transformer on no load.
- A three phase induction motor has 6 poles and runs at 960 r.p.m. on full load, it is supplied from an alternator having 4 poles and running at 1500 rpm. Calculate the Full load Slip of the induction motor.
- What is Switch fuse unit (SFU)?
- Write a short note on Mesh and Nodal Analysis.
- What is the condition for series resonance? What happens to the impedance of a series RLC circuit at resonance?
Section B – sample questions
- Explain operating principle of transformer and derive the equation for induced emf in a two-winding transformer. Also discuss the term regulation and efficiency w.r.t. transformer.
- State the significance of voltage regulation of transformer. A 4kVA, 200/400V, 50Hz single phase transformer has equivalent resistance referred to primary as 0.15Ω. Calculate: (i) Total copper losses on full load. (ii) Efficiency at full load 0.9 pf lagging. (iii) Efficiency at half load 0.8 pf leading. Assume total iron losses = 60W.
- Reduce the network of Fig. 1 to obtain the equivalent resistance as seen between nodes ad.
