Question

Time required to run emergency generators on full load weekly:

a) 1 hour
b) 2 hours
c) 3 hours
d) 4 hours

Answer 1

To run a 4.00-kW electric dryer, 40 people would be needed, and to replace an 800 MW power plant, 8,000,000 people would be required, assuming each person can generate 100 W of power.

Step-by-step explanation:

The question relates to the amount of power output that humans can produce and how many would be needed to replace conventional power sources. For instance, if a person can generate 100 watts of power, then to run a 4.00-kW electric clothes dryer, it would take 40 people as 4,000 watts divided by 100 watts per person equals 40. Similarly, to replace a large electric power plant that generates 800 MW (800,000,000 watts), it would require 8,000,000 people, as 800,000,000 watts divided by 100 watts per person equals 8,000,000.

Using this logic, it's clear that human power generation is not feasible for such large-scale applications, demonstrating the immense power that electricity provides in our daily lives and why such considerations are an important part of energy discussions.
