The video provides three examples of calculating efficiency, including a light bulb, a speaker, and an electric motor. The examples illustrate how some of the energy put into devices is wasted and transferred as thermal energy. The video highlights the importance of considering efficiency when designing and using devices that transfer energy.\n
