01Electrical circuits, machines and digital logic
This domain covers DC and AC circuit analysis, transformers and rotating machines, power converters and Boolean logic. This foundations field usually mixes a quantitative circuit problem with a simplification of a logic function.
430 words, about 2 min02Phasors, complex power and three-phase engineering models
Power-system calculations need a clearly defined electrical model. Establish whether voltages and currents are instantaneous, peak or RMS, whether the circuit is sinusoidal, and whether a three-phase load is balanced.
413 words, about 2 min03Transformers, machines and distribution-system reasoning
Distribution design connects source characteristics, loads, equipment behavior and operating scenarios. A demand estimate should use stated diversity or coincidence assumptions rather than assume that every connected device draws its nameplate input continuously.
414 words, about 2 min04Fault models, protective coordination and earthing concepts
A protection study starts by defining the network state, fault location and relevant sources. A prospective short-circuit calculation estimates current under specified fault and impedance assumptions.
403 words, about 2 min05Installation planning, measurement and evidence of compliance
Installation planning translates a design into a controlled physical arrangement. Identify the supply, load, environmental conditions, routing, interfaces and equipment instructions.
407 words, about 2 min06Measurement, feedback, PLC and automation
This domain tests whether you can describe a control loop, choose a sensor from its specifications, explain what a PLC does in each scan and justify a robot morphology. Expect questions on sensor characteristics, PID behaviour, PLC I/O and degrees of freedom.
489 words, about 2 min07Lighting models, metering and building-control integration
Lighting design should distinguish light output, illumination on a surface and energy consumption. Luminous flux is measured in lumens, while illuminance measures flux received per area in lux.
396 words, about 2 min08Engineering models, drawings, evidence and project decisions
Engineering reasoning starts with a purpose, a system boundary and the assumptions that permit a calculation. A free-body diagram, circuit diagram, energy-flow model and process chart represent different relationships.
