SUMMARY

The discussion centers on calculating the voltage and power received by a customer from an electric utility company. Given a load current of 110 A and a resistance of 0.125 Ω per 294 m for two 53.6 m copper wires, the voltage at the customer's house is determined to be 110 V. Using the formula P = V * I, the power received by the customer can be calculated as 12100 W (or 12.1 kW). This calculation is critical for understanding the efficiency of power delivery in residential settings.

PREREQUISITES
  • Understanding of Ohm's Law and power calculations
  • Familiarity with electrical resistance and its impact on voltage
  • Knowledge of basic electrical engineering concepts
  • Ability to manipulate equations involving voltage, current, and power
NEXT STEPS
  • Research the effects of wire gauge on resistance and power loss
  • Learn about voltage drop calculations in electrical circuits
  • Explore the principles of power factor in AC circuits
  • Investigate the efficiency of different types of electrical wiring materials
USEFUL FOR

Electrical engineers, utility company technicians, and students studying electrical circuits will benefit from this discussion, particularly those focused on power delivery and efficiency in residential electrical systems.

Homework Statement



8.
An electric utility company supplies a customer's house from the main power lines (115 V) with two copper wires, each of which is 53.6 m long and has a resistance of 0.125 Ω per 294 m. Calculate the voltage at the customer's house for a load current of 110 A.

Correct : 1.10E+02 V

9. [1 point, 10 tries]
For this load current, calculate the power that the customer is receiving.

?




Homework Equations



P=V*I ?

The Attempt at a Solution



I tried subbing in voltage at the house, voltage before the power lines (so 112.5 and 115 ) and these don't work...

I would take the voltage at the customer's house that you already calculated mutiplied with the load current.
