Mastering Physics Problem 30.22

 Background

Electricity is distributed from electrical substations to neighborhoods at 15000 V. This is a 60 Hz oscillating (AC) voltage. Neighborhood transformers, seen on utility poles, step this voltage down to the 120 V that is delivered to your house.




Part A
