- Ohm's Law
- For a conductor at constant temperature, current is directly proportional to applied voltage and inversely proportional to resistance, expressed as V = IR.
- Three-phase power formula
- For a balanced three-phase load, total active power equals the square root of three times line voltage times line current times power factor.
- Transformer EMF equation
- Induced EMF per winding equals 4.44 times frequency times turns times maximum flux, linking winding design directly to voltage rating.
- Synchronous speed
- The speed of the rotating magnetic field in an AC machine, equal to 120 times supply frequency divided by the number of poles.
- Slip in induction motor
- Slip is the fractional difference between synchronous speed and actual rotor speed; rotor frequency equals slip times supply frequency.
- Skin effect
- At higher AC frequencies, current concentrates near the conductor surface, raising effective resistance and reducing usable cross-section.
- Power factor correction
- Capacitor bank rating in kVAR equals active power times the difference between tangents of initial and target phase angles.
- Lap versus wave winding
- Lap winding has parallel paths equal to the number of poles; wave winding has two parallel paths regardless of pole count.
- Fundamental Rights
- Guaranteed in Part III, Articles 12 to 35, of the Indian Constitution, covering equality, freedom, exploitation, religion, culture and remedies.
- Electricity Act 2003
- Indian law that unbundled generation, transmission and distribution, created State Electricity Regulatory Commissions and replaced earlier electricity statutes.
- UPPCL
- Uttar Pradesh Power Corporation Limited, a state-owned holding company whose subsidiaries handle transmission and distribution of electricity in Uttar Pradesh.
- UPERC
- The Uttar Pradesh Electricity Regulatory Commission, which determines retail tariffs, licensing and performance standards for utilities within the state.
- PM-KUSUM scheme
- Indian government programme promoting solar pumps, decentralised solar plants and feeder solarisation to give farmers reliable daytime irrigation power.
- 42nd Amendment
- Constitutional amendment of 1976 that added Fundamental Duties under Article 51A and inserted the words socialist and secular in the Preamble.
- Reverse alphabet positions
- In reasoning codes, letters equidistant from the alphabet ends sum to 27, so A pairs with Z, B with Y and so on.
- Clock hand angle
- The angle between hour and minute hands equals the absolute value of 30H minus 5.5M degrees, where H is hour and M minutes.
- Syllogism validity rule
- A conclusion follows only if it is true in every Venn diagram satisfying the premises; a possibility is not a certainty.
- Blood relation tree
- A diagram using vertical links for parent-child generations and horizontal links for siblings and marriage, used to trace stated relationships.
- Symmetric letter series
- A series that repeats a block of letters in forward then reverse order, so the middle letters appear once and end letters twice.
- बहुव्रीहि समास
- वह समास जिसमें समस्तपद अपने दोनों पदों से भिन्न किसी तीसरे अर्थ का बोध कराता है, जैसे दशानन का अर्थ दस मुख वाला रावण।
- दीर्घ संधि
- स्वर संधि का वह भेद जिसमें अ, आ, इ, ई, उ, ऊ के बाद समान स्वर आने पर दोनों मिलकर दीर्घ स्वर बन जाते हैं।
- अनुप्रास अलंकार
- जिस अलंकार में एक ही वर्ण की आवृत्ति बार-बार होती है और उससे ध्वनि-सौंदर्य उत्पन्न होता है।
- सकर्मक क्रिया
- वह क्रिया जिसका फल कर्म पर पड़ता है और वाक्य में कर्म की आवश्यकता रहती है, जैसे राम ने पत्र लिखा।
- Subject-verb agreement
- A verb must match its subject in number and person; singular subjects take singular verbs, and intervening phrases do not change agreement.
- Second conditional
- Used for unreal or improbable present situations: if plus past simple in the condition clause, would plus base verb in the result.
- Passive voice formation
- The object becomes the subject, the verb becomes a form of be plus past participle, and the original subject follows by if retained.
- Fixed preposition collocations
- Verbs and adjectives pair with specific prepositions, such as comply with, deprived of, insist on and consist of, and must be memorised.
- Volatile versus non-volatile memory
- RAM loses stored data when power is removed and is volatile; ROM retains its contents without power and is non-volatile.
- IPv4 versus IPv6
- IPv4 uses 32-bit addresses written in dotted decimal; IPv6 uses 128-bit addresses written in hexadecimal groups separated by colons.
- OSI model layers
- Seven layers from bottom: physical, data link, network, transport, session, presentation and application, each handling defined communication tasks.
- Trojan horse
- Malicious software disguised as a legitimate program that users install voluntarily, after which it performs unauthorised actions such as data theft.
- Absolute cell reference
- An Excel reference written with dollar signs, such as $A$1, that stays fixed when the formula is copied to other cells.
