Electrical Engineering - Core Formulas and Rules
Ohm's law: V = IR; power P = VI = I²R = V²/R. In a series circuit current is common; in a parallel circuit voltage is common.
Three-phase power: P = √3 · V_L · I_L · cos φ for a balanced load; per-phase power P_ph = V_ph · I_ph · cos φ.
Transformer EMF equation: E = 4.44 · f · N · Φ_max. Turns ratio a = N1/N2 = V1/V2 = I2/I1 for an ideal transformer.
DC machine EMF: E = (P·Φ·N·Z)/(60·A) for a generator, where A = number of parallel paths (A = 2 for lap, A = 2p for wave winding).
Synchronous speed N_s = 120f/P rpm; slip s = (N_s − N_r)/N_s. Induction motor rotor frequency f_r = s·f.
Power factor correction: capacitor kVAR = P·(tan φ1 − tan φ2), where φ1 and φ2 are the initial and target phase angles.
Per-unit and efficiency: %η = (output)/(output + losses) × 100. Transformer maximum efficiency occurs when copper loss equals iron loss.
Cable and conductor sizing: voltage drop ΔV = 2·I·L·ρ/A for a two-wire DC line; skin effect raises effective AC resistance at high frequency.
General Knowledge and Current Affairs - High-Yield Anchors
Indian Constitution: adopted 26 November 1949, came into force 26 January 1950; Dr B. R. Ambedkar chaired the Drafting Committee.
Fundamental Rights are in Part III (Articles 12–35); Directive Principles in Part IV (Articles 36–51); Fundamental Duties in Article 51A, added by the 42nd Amendment (1976).
UPPCL (Uttar Pradesh Power Corporation Limited) is a state-owned holding company; its subsidiaries include UPPCL Transmission and distribution companies such as MVVNL, PVVNL, DVVNL, PuVVNL and KESCo.
Uttar Pradesh borders eight states and one union territory; its capital is Lucknow and the High Court sits at Prayagraj (Allahabad).
Renewable energy targets: India aims for 500 GW of non-fossil capacity by 2030; major schemes include PM-KUSUM for solar pumps and the National Solar Mission.
Key Indian institutions: BIS sets standards, CEA advises on electricity, CERC regulates interstate transmission, and SERC (UPERC in UP) sets retail tariffs.
Electricity legislation: the Electricity Act 2003 replaced the 1910, 1948 and 1998 laws; it unbundled generation, transmission and distribution and created SERCs.
Awards and bodies: NTPC and Power Grid are Maharatna/ Navratna CPSEs; the Bureau of Energy Efficiency runs the Standards & Labelling programme.
Reasoning and General Intelligence - Patterns and Rules
Number series: check differences, then ratios, then alternating or square/cube patterns before assuming a rule.
Coding-decoding: letter positions A=1 … Z=26; reverse alphabet pairs sum to 27 (A↔Z, B↔Y).
Blood relations: draw a family tree; vertical lines for generations, horizontal for siblings and marriage; never assume gender from a name.
Direction sense: use a compass sketch; net displacement for perpendicular moves is the hypotenuse, e.g. √(3² + 4²) = 5.
Syllogism: a conclusion is valid only if it holds in every possible Venn diagram consistent with the premises; 'some' does not imply 'all'.
Clock and calendar: hands coincide 11 times in 12 hours; angle = |30H − 5.5M| degrees. Odd-day method gives the day of the week for a date.
Analogy and classification: identify the relation type (part-whole, cause-effect, worker-tool) and apply the same relation to the options.
Seating arrangement: fix one anchor person first, then place others clockwise or anticlockwise using the stated facing direction.
General Hindi - व्याकरण और शब्द-ज्ञान
संधि: स्वर संधि (दो स्वरों के मेल से), व्यंजन संधि और विसर्ग संधि - जैसे विद्या + आलय = विद्यालय (दीर्घ संधि)।
समास के भेद: अव्ययीभाव, तत्पुरुष, कर्मधारय, द्विगु, द्वंद्व और बहुव्रीहि; बहुव्रीहि में समस्तपद किसी तीसरे अर्थ का बोध कराता है।
उपसर्ग और प्रत्यय: उपसर्ग शब्द के आरम्भ में, प्रत्यय अंत में जुड़ता है; जैसे अनु + शासन = अनुशासन, लड़क + पन = लड़कपन।
संज्ञा के भेद: व्यक्तिवाचक, जातिवाचक, भाववाचक, समूहवाचक और द्रव्यवाचक।
वाक्य शुद्धि: कर्ता-क्रिया का लिंग, वचन और पुरुष में अन्वय होना चाहिए; कर्म के अनुसार सकर्मक और अकर्मक क्रिया।
अलंकार: अनुप्रास (वर्णों की आवृत्ति), उपमा (समानता), रूपक (अभेद आरोप), यमक (एक शब्द भिन्न अर्थ में दोहराया जाना)।
मुहावरे और लोकोक्तियाँ अर्थ सहित याद करें; जैसे 'आँख का तारा' का अर्थ है अत्यंत प्रिय व्यक्ति।
वर्तनी और शब्द-शुद्धि: 'क्ष', 'त्र', 'ज्ञ' संयुक्त व्यंजन हैं; शुद्ध रूप जैसे 'पूर्ण', 'अत्यधिक', 'विद्यार्थी' ध्यान रखें।
General English - Grammar and Usage Rules
Subject-verb agreement: a singular subject takes a singular verb; 'each', 'every', 'either' and 'neither' are singular.
Articles: 'a' before consonant sounds, 'an' before vowel sounds (an hour, a university); 'the' for unique or previously specified nouns.
Tenses: present perfect (has/have + past participle) links past action to the present; past perfect marks the earlier of two past actions.
Active to passive: object becomes subject, verb becomes be + past participle, agent introduced by 'by'.
Conditionals: second conditional uses 'if + past simple, would + base verb'; third conditional uses 'if + past perfect, would have + past participle'.
Prepositions with fixed collocations: 'comply with', 'deprive of', 'insist on', 'consist of', 'prefer to'.
Direct to indirect speech: change tense one step back, change pronouns per the reporting verb, and adjust time/place words (now → then, here → there).
Common error traps: 'one of the + plural noun + singular verb'; 'neither … nor' follows the nearer subject for verb agreement.
Computer Knowledge - Fundamentals and Shortcuts
Memory units: 1 byte = 8 bits; 1 KB = 1024 bytes; 1 MB = 1024 KB; 1 GB = 1024 MB. ROM is non-volatile; RAM is volatile.
Number systems: binary base 2, octal base 8, decimal base 10, hexadecimal base 16; hex digits A–F equal 10–15.
Shortcuts: Ctrl+C copy, Ctrl+V paste, Ctrl+X cut, Ctrl+Z undo, Ctrl+Y redo, Ctrl+S save, Ctrl+P print, Ctrl+F find.
IP addressing: IPv4 is 32-bit, IPv6 is 128-bit; DNS resolves domain names to IP addresses; DHCP assigns IP addresses automatically.
OSI model has seven layers; TCP operates at the transport layer and IP at the network layer. HTTP default port 80, HTTPS 443, FTP 21.
Malware types: virus attaches to files, worm self-replicates across networks, Trojan disguises as legitimate software, ransomware encrypts data for payment.
MS Excel: a formula begins with '='; SUM, AVERAGE, COUNT and IF are common functions; a cell reference like A1 is relative, $A$1 is absolute.
Generations: first generation used vacuum tubes, second transistors, third integrated circuits, fourth microprocessors, fifth artificial intelligence.
