Covers magnetism, electricity, and electrical circuit fundamentals — Ohm's Law, Coulomb's Law, Faraday's Law — the basic electrical theory underlying every relay, motor, and circuit used in signalling equipment.
Key Points
- Faraday's Law of electromagnetic induction is the working principle behind relay operation — a core, examinable link between theory and applied signalling equipment.
