133 Tesla Edison and the Alternating Current - One Minute History

Nikola Tesla was hired by Thomas Edison in New York City, where he admired Edison. However, they disagreed on electricity types: Edison supported direct current (DC), while Tesla favored alternating current (AC). Their partnership turned into a rivalry when Tesla improved Edison's DC motor and generator, but Edison dismissed his offer of $50,000 as a joke. Tesla resigned and joined Westinghouse, Edison's competitor. The rivalry between Edison and Westinghouse over electricity efficiency ended with AC becoming the standard due to its ability to travel long distances and transfer to higher voltages.

What was the main point of contention between Tesla and Edison?

• The cost of electricity

• The design of light bulbs

• The type of electrical current to use

• The location of their headquarters

What did Edison promise Tesla if he improved the DC motor and generator?

• A patent

• A monetary reward

• A partnership

• A promotion

Why did Tesla resign from working with Edison?

• He wanted to start his own company

• He disagreed with Edison's management style

• Edison refused to pay the promised reward

• He was offered a better position elsewhere

Who did Tesla work for after leaving Edison?

• General Electric

• Philips

• Westinghouse

• Siemens

Why did alternating current (AC) become the standard for electricity distribution?

• It was easier to understand

• It could travel long distances and transfer to higher voltages

• It was safer for home use

• It was cheaper to produce
