Answer & Solution
Answer: Option D
Solution:
Electric traction refers to the use of electric power to propel vehicles such as trains, trams, and electric buses. It offers several advantages over other methods of traction:
1. Faster acceleration: Electric traction systems can provide high torque at low speeds, allowing for faster acceleration of vehicles compared to diesel or steam-powered traction.
2. No pollution problems: Electric traction systems produce less or zero emissions at the point of use, contributing to cleaner air quality and reduced environmental impact compared to diesel or steam engines.
3. Better braking action: Electric traction systems can employ regenerative braking, where energy from braking is captured and fed back into the power supply system, improving efficiency and reducing wear on braking components.
Option A: Faster acceleration is correct because electric traction systems generally offer faster acceleration due to the characteristics of electric motors.
Option B: No pollution problems is correct because electric traction systems are cleaner and produce fewer emissions compared to diesel or steam-powered traction.
Option C: Better braking action is correct because electric traction systems can utilize regenerative braking, which is more efficient and provides better control over braking compared to traditional friction brakes.
Therefore, the correct answer is
All of the above
