Question

what is the primary purpose of a turbine in the process of electricity generation? it converts high pressure steam into energy by spinning the central shaft. it heats water to generate steam. it brings electricity from the generator to homes and other buildings.

Explanation:

To determine the primary purpose of a turbine in electricity generation, we analyze each option:

• The first option: Turbines use high - pressure steam to spin, which then drives the central shaft connected to the generator. This is consistent with how turbines function in power generation (converting steam energy to mechanical energy for the generator).
• The second option: Heating water to generate steam is the job of a boiler (using the fuel source), not the turbine.
• The third option: Power lines are responsible for transmitting electricity from the generator to homes and buildings, not the turbine.

Answer:

A. It converts high pressure steam into energy by spinning the central shaft.
