BCS Written EEE (892) study guide
BCS Written EEE (892) · Work through your exam, one topic at a time.
The BCS Written Examination for Electrical and Electronic Engineering (often cited as BCS 892) is a descriptive, subject-wise written assessment used in Bangladesh Civil Service recruitment for engineering candidates. It is intended for graduates in electrical and electronic engineering who are competing for cadre posts where technical judgement, not just recall, is being tested. The BCS Written EEE (892) study guide has 11 sections and about 3,215 words.
01Electrical Circuits and Network Analysis
Master Ohm's and Kirchhoff's laws first, then mesh and nodal analysis, superposition, Thevenin and Norton equivalents, and maximum power transfer. Be fluent with phasors, impedance, resonance, and power factor in single-phase AC, and with three-phase star/delta relations.
268 words, about 1 min02Electrical Machines and Transformers
Understand transformer EMF equation E = 4.44 f N Phi, turns ratio, equivalent circuit referral, losses (core vs copper), efficiency and regulation, and why open-circuit and short-circuit tests separate the two loss components. For DC machines, grasp the EMF equation, armature reaction, commutation, and the different torque-speed characteristics of shunt, series, and compound motors.
260 words, about 1 min03Power Systems: Generation, Transmission, Distribution, Protection
Cover per-unit calculations, transmission-line models (short, medium pi/T, long), surge impedance, and voltage regulation. Know generation economics: load factor, diversity factor, tariff structures, and economic load dispatch.
238 words, about 1 min04Power Electronics and Drives
Know the semiconductor switches (diode, SCR, MOSFET, IGBT) and their safe operating areas, then the converter families: uncontrolled and controlled rectifiers, choppers, inverters, and AC voltage controllers. Understand firing angle effects on average output voltage, ripple, and power factor.
252 words, about 1 min05Control Systems and Instrumentation
Understand transfer functions, block-diagram reduction, and signal-flow graphs. Master time response (first and second order: damping ratio, natural frequency, overshoot, settling time) and steady-state error via system type.
225 words, about 1 min06Electronic Devices, Circuits and Analog Electronics
Cover diode models and applications (rectifiers, clippers, clamps, Zener regulation), BJT configurations and biasing, small-signal hybrid parameters, and FET operation. Study feedback topologies (voltage-series etc.), gain and input/output impedance effects, and oscillator conditions (Barkhausen criterion).
240 words, about 1 min07Digital Electronics
Master number systems and codes (binary, BCD, Gray, two's complement), Boolean algebra and Karnaugh maps, and combinational building blocks: adders, multiplexers, decoders, comparators. Then sequential logic: latches, flip-flops, counters, shift registers, and state machines.
237 words, about 1 min08Microprocessors and Embedded Systems
Understand microprocessor architecture: ALU, registers, control unit, buses, and memory mapping. Know instruction formats, addressing modes, and the fetch-decode-execute cycle.
216 words, about 1 min09Communication Systems and Signal Processing
Cover analog modulation (AM, FM) and their bandwidths, then digital modulation (ASK, FSK, PSK, QAM) and error performance. Study sampling theorem, quantisation, PCM, and line coding.
219 words, about 1 min10Computer Networks
Know the OSI and TCP/IP models and which protocol sits at each layer. Study framing, error detection (parity, checksum, CRC), and flow control (stop-and-wait, sliding window).
208 words, about 1 min11Software and ICT Applications
Understand programming fundamentals (variables, control flow, functions, arrays), data structures (stack, queue, list, tree), and algorithm basics (sorting, searching, complexity). Know software engineering concepts: SDLC models, testing levels, version control, and documentation.
