Electrical
Generating, transmitting, converting and using electrical power — circuits, machines, power systems, protection, power electronics and control.
Electrical engineering deals with energy at scale: the circuits that analyse it, the machines that convert it, the grids that carry it, the electronics that control it and the safety systems that protect people and equipment.
This domain covers circuit analysis, AC circuits, three-phase systems, electromagnetism, electrical machines, power systems, protection, power electronics, control systems, measurements, installation and safety, and electric vehicles.
Subjects (12)
Circuit Analysis
Systematic methods and theorems for solving any linear circuit — nodal and mesh analysis, Thevenin, Norton and superposition.
AC Circuits
Sinusoidal voltages and currents, phasors, impedance, power factor and resonance.
Three-Phase Systems
Three sinusoidal voltages 120° apart — the standard way to generate, transmit and use large amounts of power.
Electromagnetism
Magnetic fields, flux, induction and magnetic circuits — the physics behind every motor, generator and transformer.
Electrical Machines
Transformers, DC machines, induction motors, synchronous machines and special motors — converting between electrical and mechanical energy.
Power Systems
How electricity is generated, transmitted and distributed — from power stations to the wall socket.
Protection and Switchgear
Fuses, circuit breakers, relays and earthing that detect faults and isolate them quickly and selectively.
Power Electronics
Converting and controlling electric power efficiently with semiconductor switches — rectifiers, DC–DC converters and inverters.
Control Systems
Feedback systems that make machines and processes behave as intended — modelling, response, stability and PID control.
Electrical Measurements
Instruments and methods for measuring voltage, current, power, energy, resistance and insulation.
Electrical Installation and Safety
Wiring buildings safely — cables, earthing, protective devices, regulations and safe working practice.
Electric Vehicles
Battery packs, traction motors, inverters and charging — the electrical engineering inside EVs.
