Review Questions

• How did Thomas Edison's approach to invention and research differ from previous methods used by inventors?
  • Edison's approach to invention involved systematic experimentation and collaboration within a dedicated research laboratory setting. Unlike previous inventors who often worked alone, he created an environment that encouraged teamwork and leveraged a variety of scientific disciplines. This led to more efficient development processes and a higher rate of successful inventions, fundamentally changing how innovations were produced in electrical engineering.
• Discuss the impact of Edison's invention of the incandescent light bulb on society and the electrical engineering field.
  • Edison's development of the incandescent light bulb transformed everyday life by making electric lighting practical and accessible. This innovation not only improved safety and convenience in homes and businesses but also catalyzed the growth of electric power infrastructure. It led to increased demand for electrical engineers and technicians, shaping the future direction of the electrical engineering profession as a whole.
• Evaluate how Thomas Edison's rivalry with Nikola Tesla influenced the evolution of electrical engineering practices and standards.
  • The rivalry between Edison and Tesla significantly shaped electrical engineering by creating a competitive atmosphere that drove innovation in power systems. Edison's promotion of direct current (DC) faced strong opposition from Tesla's alternating current (AC) system, which ultimately proved more efficient for long-distance transmission. This 'War of Currents' forced engineers to critically assess power distribution methods, leading to the widespread adoption of AC systems today. The outcomes from this rivalry not only impacted technical standards but also highlighted the importance of competition in fostering advancements within the field.
