AC/DC

Front

What is AC?

Back

AC stands for Alternating Current, which is an electric current that reverses direction periodically.

Front

What is DC?

Back

DC stands for Direct Current, which is an electric current that flows in one direction only.

Front

Who is known for the development of AC power systems?

Back

Nikola Tesla is known for the development of AC power systems.

Front

Who is known for the development of DC power systems?

Back

Thomas Edison is known for the development of DC power systems.

Front

What is renewable energy?

Back

Renewable energy is energy produced from natural resources that replenish themselves, such as solar, wind, and hydro power.

Front

What is the primary advantage of AC over DC for power transmission?

Back

AC can be easily transformed to higher voltages, allowing it to be transmitted over long distances with less energy loss.

Front

What is the primary disadvantage of DC?

Back

DC is not easily transformed to higher voltages, making it less efficient for long-distance transmission.

Front

What is the role of transformers in AC systems?

Back

Transformers are used to increase or decrease the voltage of AC electricity for efficient transmission.

Front

What is the significance of the 'War of Currents'?

Back

The 'War of Currents' was a competition between AC and DC systems for dominance in electrical power distribution.

Front

What is a common use of DC power?

Back

DC power is commonly used in batteries and electronic devices.
