Electric Engines and How They Work

What is the operating principle behind most modern electric vehicles?

• Fuel and air combustion

• Magnetism

• Mechanical crankshaft

• Electromagnetism

In 1834, a Dutch professor named Sebranda Stratting built his own small electric vehicle. What was unique about its battery?

• It was rechargeable

• It was non-rechargeable

• It used fuel and air combustion

• It used magnetism

How do internal combustion engines work?

• By using magnetism

• By converting linear motion into rotary motion

• By reversing the polarity of the magnet

• By compressing and igniting fuel and air

What is the fundamental principle that drives electric cars?

• Mechanical crankshaft

• Fuel and air combustion

• Magnetism

• Electromagnetism

How does an inverter module in an electric vehicle work?

• By converting direct current to alternating current

• By converting alternating current to direct current

• By reversing the polarity of the magnet

• By compressing and igniting fuel and air

Why do electric powertrains have advantages over internal combustion engines?

• They require less maintenance

• They have better control over speed and torque

• They generate electricity while in motion

• All of the above

What happens when the shaft-mounted magnet or rotor in an electric vehicle is spun?

• It generates electricity

• It requires maintenance

• It converts linear motion into rotary motion

• It compresses and ignites fuel and air

What is the name of the car company in California that is known for its advancements in electric motor design?

• Nikola Tesla

• Sebranda Stratting

• Groningen Netherlands

• Internal Combustion Engines Inc.

What is the purpose of an inverter in an electric vehicle?

• To generate electricity

• To convert direct current to alternating current

• To convert alternating current to direct current

• To reverse the polarity of the magnet

Why don't domestic electric motors require an inverter?

• Because they use fuel and air combustion

• Because they have a mechanical crankshaft

• Because they use magnetism

• Because they use alternating current
