1) What is the first step in generating electricity according to the video? a) Turning on a light switch in a dark room b) Building the electricity grid c) Starting at the source, such as natural resources provided by nature d) Increasing the voltage with transformers 2) Which of the following energy sources is considered unlimited? a) Coal b) Natural gas c) Oil d) Wind power 3) What role does steam play in thermal power plants? a) It powers a turbine which then generates electricity b) It stores electricity for later use c) It increases voltage for transmission d) It transports electricity from power plants to homes 4) Why can't current technology cost-effectively store large amounts of electricity? a) Because electricity must be generated to meet demand at all times rather than stored b) Because transformers reduce the voltage c) Because renewable energy sources are unreliable d) Because long-distance transmission lines are inefficient 5) What is the primary function of a transformer in the electricity grid? a) To generate electricity from mechanical energy b) To increase or decrease voltage levels for efficient transmission and distribution c) To store electrical energy for later use d) To convert AC electricity into DC electricity 6) Why is it important that the amount of electricity generated matches the demand at all times? a) Because excess electricity is stored for later use b) Because the grid only transmits electricity during peak hours c) Because too much or too little power can cause blackouts or system crashes d) Because transformers only operate at a fixed power level 7) Which of the following best describes the electricity grid? a) A single power plant generating all electricity for Australia b) An interconnected network of power plants and transmission lines managing electricity delivery c) A device that steps down voltage for household use d) An energy storage facility for excess electricity 8) What happens to electricity's voltage as it travels from power plants to homes? a) It remains constant until it reaches your breaker box b) It is decreased immediately after generation c) Voltage changes only once at the substation near your neighborhood d) It is increased for long-distance transport, then decreased for local use
