La guerra de las corrientes

In the 19th century, Nikola Tesla and Thomas Edison competed for control of the American electricity market. Edison initially dominated with direct current (DC), but it had limitations in energy transmission over long distances. Tesla introduced alternating current (AC), which could transmit power over greater distances. Edison launched a smear campaign against AC, even funding the development of the electric chair to associate AC with danger. Despite his efforts, AC became the primary form of electrical supply, cementing Tesla's legacy in the War of Currents.

What was the main disadvantage of Edison's direct current system?

• It was not safe for home use.

• It lost energy over long distances.

• It could not be used for lighting.

• It was too expensive to produce.

Who partnered with Tesla to commercialize alternating current?

• Alexander Graham Bell

• Thomas Edison

• Henry Ford

• George Westinghouse

What tactic did Edison use to discredit alternating current?

• He claimed it was too expensive.

• He demonstrated its dangers by electrocuting animals.

• He said it was not efficient.

• He argued it was outdated technology.

What was Edison's secret hope in funding the electric chair?

• To prove alternating current was safe.

• To associate alternating current with danger.

• To promote direct current as more efficient.

• To support capital punishment.

What is the primary form of electrical supply today?

• Direct current

• Solar power

• Nuclear power

• Alternating current
