FAEN 106: Applied Electricity

Foundations of electricity: charge, voltage, current, power and energy, computation of power and 
energy for electrical gadgets and household, simple billing calculations. Electricity supply: 
definition and characteristics of AC and DC voltages and currents and their applications, 
calculation of Instantaneous, RMS and Average voltage and current values and their relevance. 
Transformer: definition and components of a transformer, principle of operation, ideal transformer 
and characteristics, transformer types and ratings used by utilities in Ghana. AC circuit systems: 
definition of 1-phase 2-phase and 3-phase circuit systems, voltage and current relationship 
between the circuit systems, sample voltage drop and line loss calculation for electricity supply 
from source to destination. Electricity supply: electricity utilities and functional roles, electricity 
generation sources, hydro power generation process, transmission process, distribution process to 
users in Ghana. Power factor: definition and relevance, active power, reactive power, and apparent 
power, calculation of power factor and correction. Electric Motors: components of an electric 
motor, basic principle of operation, motor types and applications. Electrical Safety: importance of 
electrical safety, shock current, common sources of hazards, safe practices.
