Engineer Electricity study guide
Engineer Electricity · Work through your exam, one topic at a time.
The Engineer Electricity credential is a professional certification that assesses whether a candidate can practise electrical engineering at a responsible-charge level. It suits practising electrical engineers, plant and utility engineers, consulting designers, and graduates moving from academic study into accountable engineering work. The Engineer Electricity study guide has 10 sections and about 3,108 words.
01Electrical Circuit Theory and Analysis
Circuit Theory and Analysis checks whether you can apply Kirchhoff's laws, reduce networks, analyse first-order transients, and handle AC and three-phase power with correct sign conventions. KCL: the algebraic sum of currents at a node is zero.
368 words, about 2 min02Electromagnetic Fields and Waves
This domain tests Maxwell's equations, boundary conditions, plane-wave propagation, transmission-line behaviour, and loss mechanisms such as skin effect. Maxwell equations in time form: curl E = -dB/dt, curl H = J + dD/dt, div D = rho, div B = 0.
323 words, about 2 min03Electrical Machines and Transformers
Expect questions on transformer equivalent circuits and tests, DC machine equations, induction motor slip and torque, synchronous machine excitation, losses, and efficiency. Transformer EMF: E = 4.44 f N Phi m.
311 words, about 2 min04Power Systems: Generation, Transmission, and Distribution
This domain covers per-unit modelling, line parameters, load flow, voltage regulation, stability, and distribution practice. Per-unit base: Z base = V base^2/S base.
297 words, about 1 min05Power System Protection and Switchgear
Questions cover CTs and VTs, relay characteristics, coordination, breaker ratings, arc interruption and protective schemes for generators, transformers, feeders and motors. Overcurrent relays coordinate by time and current grading.
303 words, about 2 min06Power Electronics and Drives
This domain tests controlled rectifiers, choppers, inverters, AC and DC drives, harmonics, and commutation. A thyristor conducts after a gate pulse when forward-biased and turns off when current falls below holding level.
274 words, about 1 min07Control Systems and Automation
Expect transfer functions, transient and steady-state response, stability criteria, PID control, and automation topics such as PLC scan cycles and SCADA architecture. A linear time-invariant system is described by its transfer function G(s) = output/input with zero initial conditions.
301 words, about 2 min08Electrical Measurements and Instrumentation
This domain covers analogue and digital instruments, bridges, instrument transformers, transducers, calibration, and measurement error. PMMC movement responds to average current and has a uniform scale; moving-iron instruments respond to RMS and suit AC and DC but have non-uniform scales.
280 words, about 1 min09Electrical Installation, Wiring, and Safety Codes
This domain tests protective earthing, automatic disconnection, cable sizing, protective-device selection, isolation, IP ratings and compliance with installation codes such as IEC 60364, BS 7671 or NEC NFPA 70 depending on jurisdiction. Automatic disconnection of supply requires the earth-fault loop impedance to be low enough for the protective device to trip within the disconnection time.
345 words, about 2 min10Engineering Economics, Project Management, and Professional Ethics
This domain covers investment appraisal, cost comparison, project scheduling, earned value, and the ethical duties of an engineer. NPV discounts all cash flows at the required rate: NPV = sum of CF t/(1+r)^t.
