Nikola Tesla

What was the significance of this animal in Tesla's life?

• It was given to Tesla by Thomas Edison

• It accompanied young Tesla on his journey to America

• It inspired young Tesla to study electricity

• It prevented young Tesla from being electrocuted

The word "alternating" in "alternating current" refers to:

• The voltage levels transmitted through power lines

• The opposite directions in which electrical generators spin

• The levels of resistance supplied by insulated wires

• The flow of electrons through circuits

What was the primary reason why Thomas Edison preferred direct current to alternating current?

• He thought alternating current wouldn't work

• He'd make more money from direct current electrical systems

• He thought alternating current systems would prove too expensive to install

• He thought direct current was safer

What advantage does AC power have over DC power?

• AC is practical to distribute at high voltage

• AC is completely safe at any voltage

• AC can be used to power handheld devies

• AC doesn't require wires for delivery to homes

Cities that switched from DC to AC power probably became:

• More at risk for electrical fires

• Less well-lit

• Less polluted

• Wealthier

Which term best describes George Westinghouse's relationship with Nikola Tesla?

• Rival

• Sponsor

• Best Friend

• Mentor

Which statement about this transformer is true?

• The left coil will have a higher voltage than the right coil

• The left coil and the right coil will have the same voltage

• The left coil will have a lower voltage than the right coil

• High voltage from the power source will be converted to a voltage that's safe for home use

Which of the following devices wouldn't have been invented without the Tesla coil?

• 
• 
• 
• 

An induction motor's rotor is propelled by:

• An electric current

• Magnetic repulsion

• A chain or belt

• A transformer

Which statement describes Nikola Tesla's legacy?

• He designed the first electric motor

• He built the first electrical distribution system

• He helped replace DC power with AC power

• He discovered alternating current
