Q10 Physics Sinusoidal AC Unit 3 - AOS 3

Question 10

1 mark

Two AC generators, Generator X and Generator Y, produce sinusoidal voltages. Generator X has a peak-to-peak voltage of 10 V and a frequency of 50 Hz. Generator Y has a peak-to-peak voltage of 20 V and a frequency of 100 Hz. Which of the following statements correctly compares the voltages produced by the two generators?

Your Answer

A

The amplitude of Generator X is twice that of Generator Y, and the period of Generator X is half that of Generator Y.

B

The amplitude of Generator Y is twice that of Generator X, and the period of Generator Y is half that of Generator X.

C

The amplitude of Generator X is half that of Generator Y, and the period of Generator X is half that of Generator Y.

D

The amplitude of Generator Y is four times that of Generator X, and the period of Generator Y is twice that of Generator X.

Unit 3 Overview

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.

How are fields used in electricity generation?

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.

Key Knowledge Detail

Compare sinusoidal AC voltages produced as a result of the uniform rotation of a loop in a constant magnetic field with reference to frequency, period, amplitude, peak-to-peak voltage (Vp–p) and peak-to-peak current (Ip–p).
