Question 1: power systems

Q1: Calculate the power factor of a load consuming 10 kW at 220V with current 50A.

Solution:

Apparent Power (S) = V × I = 220V × 50A = 11,000 VA = 11 kVA
Real Power (P) = 10 kW
Power Factor = P / S = 10 / 11 = 0.909 (lagging)

Gate-linked prep notes (2026)

For PSU-style hiring, candidates often combine GATE fundamentals with company aptitude/technical screens:

Revise core branch subjects (not only coding)
Practice numerical aptitude at campus-placement speed
Revisit previous technical MCQs on this site
Keep document readiness (gate scorecard if applicable, marksheets)

Extra technical drill

Q: Why do many PSU drives still test engineering fundamentals heavily?

Roles are often engineering-core, not pure software-product SDE. Expect thermodynamics / power systems / electronics / strength of materials style depth depending on your discipline, plus aptitude.

Q: Should CSE students ignore GATE topics for NTPC?

Not entirely. OS, DBMS, networks, and DSA still appear in technical rounds. Pair them with the aptitude mock on this site.
