Review Questions

• How did the development of electricity influence communication systems in the late 19th century?
  • The development of electricity significantly transformed communication systems during the late 19th century by enabling technologies like the telegraph. This system allowed for instant messaging over long distances through electrical signals, which was revolutionary compared to previous methods. The increased speed and efficiency of communication facilitated business operations, news distribution, and personal correspondence, ultimately changing how society interacted.
• Analyze the impact of electricity on urbanization during the Industrial Revolution.
  • Electricity had a profound impact on urbanization during the Industrial Revolution by powering streetcars and subways, which made cities more accessible. This improved public transportation allowed more people to live further away from their workplaces, contributing to population growth in urban areas. As cities expanded due to increased mobility, they also became centers for economic activity, innovation, and cultural exchange, further accelerating urban development.
• Evaluate the contributions of key figures like Thomas Edison and Nikola Tesla to the advancement of electricity and its applications in society.
  • Thomas Edison and Nikola Tesla made significant contributions to the advancement of electricity that shaped modern society. Edison's development of the light bulb and creation of the first electrical power station laid the groundwork for widespread electric use. In contrast, Tesla's advocacy for alternating current (AC) provided a more efficient means for transmitting electricity over long distances. Their innovations not only revolutionized technology but also facilitated industrial growth, altered daily life, and spurred new industries related to electricity.
