This module starts by looking at electrical charge and how electricity is created, before moving on to look at resistors, capacitors and inductors. The construction and identification of each component is described before their uses, properties and characteristics are studied. To aid theoretical information explained later in the module, where the operation of generators, motors and transformers is explored, the principles of magnetism and induction are studied. A look at DC generators and motors then completes the DC element of electrical fundamentals.  

Alternating current (AC) theory starts by investigating how the passive components discussed within the DC element of the module behave in AC circuits. The relationship between: resistance, reactance and impedance; voltage, current and impedance; and reactive, true and apparent power are examined. These fundamental relationships are then applied to explain the construction and operation of filter circuits.  

Magnetism and induction is then revisited for transformers before the final section which covers the theoretical aspects of AC generators and motors.
