City & Guilds 2365 / 5357 Electrical Science 3D Hub
This syllabus directory maps core UK electrical apprenticeship qualification units (City & Guilds 2365 Unit 202 & Unit 302, C&G 5357, and EAL Diploma modules) directly to our interactive 3D WebGL physics simulations. Every lab is 100% free, requires no login, and includes ready-to-use HTML embed snippets for college Virtual Learning Environments (Moodle, Blackboard, Canvas).

Understanding magnetic field generation, magnetic flux density (B), magnetising force (H), core saturation, and hysteresis losses in electrical laminations.
AC Waveforms, Phasors & Power Factor
Visualising sinusoidal alternating voltage, phase angle displacement (leading/lagging), active vs reactive power (kW vs kVAr), and power factor correction.
Three-Phase Systems & Rotating Magnetic Fields
Demonstrating how three 120° phase-displaced currents produce a constant-amplitude rotating stator magnetic field (RMF) that drags the rotor into synchronous slip.
Single-Phase Motors & Capacitor Phase Splitting
How a single-phase supply creates a pulsating field with zero starting torque, and how run/start capacitors induce the 90° auxiliary phase shift required for rotation.
Transformer Principles, Mutual Induction & Losses
Faraday’s law of induction, primary/secondary turns ratios, eddy current laminations, hysteresis loops, and real-world copper/iron loss partitioning.
RCD Toroidal Current Balancing & Tripping Physics
Kirchhoff’s first law in practice: toroidal core magnetic flux cancellation under balanced load, and instantaneous differential flux tripping the search coil under 30mA leakage.
MCB Thermal Bimetal vs Magnetic Solenoid Tripping
Inverse-time thermal bending under sustained overloads versus instantaneous electromagnetic solenoid plunger tripping under short-circuit prospective fault currents.
Arc Fault Detection (AFDD) Microcontroller Physics
Detecting erratic high-frequency current signatures of series and parallel electrical arcing before insulation ignition occurs.
Direct-On-Line (DOL) Contactor Control Circuits
Holding contacts, no-volt release latching circuits, thermal overload interlocks, and BS EN 60204-1 emergency stop Category 0 isolation.
