Question

what was a significant societal impact of his alternating current (ac) system? slowed the adoption of household appliances powered homes and industries, driving urban growth decreased industrial reliance on electrical power restricted electricity to rural areas only

Explanation:

The alternating current (AC) system, as developed by Nikola Tesla, had several significant impacts. AC can be transmitted over long distances efficiently. This allowed for powering homes and industries. Urban areas grew as they could access reliable electricity for various needs like lighting, machinery in factories, and later household appliances. Let's analyze each option:

• "Slowed the adoption of household appliances": AC actually facilitated the use of appliances as it provided a stable power source. So this is incorrect.
• "Powered homes and industries, driving urban growth": AC's ability to be transmitted over long - distance (using transformers to step - up and step - down voltage) meant that power plants could be located away from consumption centers. Homes got electricity for lighting, heating, etc., and industries for machinery. This led to urban areas becoming more populated as people moved for jobs in powered industries and to live in powered homes. This is correct.
• "Decreased industrial reliance on electrical power": AC increased industrial reliance as it provided a more efficient and scalable power source. So this is incorrect.
• "Restricted electricity to rural areas only": AC was used in both urban and rural areas (though urban areas might have adopted it more quickly at first due to infrastructure). But the key is that it was not restricted to rural areas. So this is incorrect.

Answer:

powered homes and industries, driving urban growth
