Motors and Generators > Generating Large Scale Power
Generators are used to provide large scale power production
Students learn to:
- describe the main components of a generator
- compare the structure and function of a generator to an electric motor
- describe the differences between AC and DC generators
- discuss the energy losses that occur as energy is fed through transmission lines from the generator to the consumer
- assess the effects of the development of AC generators on society and the environment
Students:
- plan, choose equipment or resources for, and perform a first-hand investigation to demonstrate the production of an alternating current
- gather secondary information to discuss advantages/disadvantages of AC and DC generators and relate these to their use
- analyse secondary information on the competition between Westinghouse and Edison to supply electricity to cities
- gather and analyse information to identify how transmission lines are:
