A student is comparing the output of two generators. Both generators have the same coil size and rotation speed within an identical magnetic field. Generator X uses slip rings, while Generator Y uses a split-ring commutator. Which statement correctly identifies the key difference in the voltage produced by the two generators?
Generator X produces a constant DC voltage, while Generator Y produces an alternating AC voltage.
Generator X produces an alternating AC voltage, while Generator Y produces a pulsating DC voltage.
Generator X produces a higher peak voltage than Generator Y.
Generator X produces a lower frequency voltage than Generator Y.

In this unit students use Newton’s laws to investigate motion in one and two dimensions. They explore the concept of the field as a model used by physicists to explain observations of motion of objects not in apparent contact. Students compare and contrast three fundamental fields – gravitational, magnetic and electric – and how they relate to one another. They consider the importance of the field to the motion of particles within the field. Students examine the production of electricity and its delivery to homes. They explore fields in relation to the transmission of electricity over large distances and in the design and operation of particle accelerators. A student-designed practical investigation involving the generation of primary data and including one continuous, independent variable related to fields, motion or light is undertaken either in Unit 3 or Unit 4, or across both Units 3 and 4, and is assessed in Unit 4, Outcome 2. The design, analysis and findings of the investigation are presented in a scientific poster format.
In this area of study, students use empirical evidence and models of electric, magnetic and electromagnetic effects to explain how electricity is produced and delivered to homes. They explore the transformer as critical to the performance of electrical distribution systems in minimising power loss.
Explain the production of DC voltage in DC generators and AC voltage in alternators, including the use of split ring commutators and slip rings respectively.
