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. Ohm's law, Kirchhoff's laws (meshes and nodes), voltage divider, and Thévenin (V th = open-circuit voltage, R th is found by deactivating independent sources appropriately while retaining dependent-source relations; a test source may be necessary). Power P = V·I = I²·R.
430 words, about 2 min02Measurement, 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. Key specifications: range, sensitivity (Δoutput/Δinput), resolution (smallest detectable change), precision, accuracy, linearity, hysteresis, response time. Typical sensors: PT 100, thermocouple, thermistor; potentiometer, encoder, inductive and limit switches; pressure, flow and level sensors; photoelectric cells.

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. Before inserting numbers, identify inputs, outputs, constraints and the physical meaning of every quantity. An ideal model is useful because it isolates a mechanism; it is not a statement that friction, heat loss, tolerances or measurement error vanish in a real installation.
