Syllabus content and objectives
Official WAEC Applied Electricity or Basic Electricity outline · Section A (For all candidates)
Content
Fundamentals of magnetism, Concept of Electric field, Capacitors, Electromagnetic field, Self and Mutual Induction
Objective
Types of magnet; magnetic flux, flux density, permeability, mmf and reluctance. Electric field properties (flux, flux density, field strength, permittivity, dielectric constant, potential gradient). Comparison between magnetic and electric circuits. Capacitor types, capacitance, dielectric, charge, series/parallel connections, voltage rating, and stored energy calculations ($E=\frac{1}{2}QV=\frac{1}{2}CV^2$). Magnetic field around current-carrying conductor, Fleming's Right Hand Rule, force ($F=BIL\sin\theta$), Lenz's/Faraday's laws, induced emf ($E=BLV\sin\theta$). Qualitative treatment of self/mutual induction, stored coil energy ($E=\frac{1}{2}LI^2$), and applications (electric bell, security alarm, solenoid, loudspeaker, buzzer, moving-coil instruments).
