The wiring in the wall of your house to and from an outlet has a total resistance
Question:
The wiring in the wall of your house to and from an outlet has a total resistance of typically 0.10 Ω. Suppose a device plugged into a 120 V outlet draws 10.0 A of current.
a. What is the voltage drop along the wire?
b. How much power is dissipated in the wire?
c. What is the voltage drop across the device?
d. At what rate does the device use electric energy?

Step by Step Answer:
Lets solve each part of the question step by step a The voltage drop along the wire can be calculated using Ohms law which relates voltage V current I and resistance R V I R Given Current I 100 A Resistance of the wire R 010 V 100 A 010 V 10 V So the voltage drop along the wire is 10 V b To calculate ...View the full answer

I teach Statistics and Probability for students of my university ( Univerisity Centroamerican Jose Simeon Canas) in my free time and when students ask for me, I prepare and teach students that are in courses of Statistics and Probability. Also I teach students of the University Francisco Gavidia and Universidad of El Salvador that need help in some topics about Statistics, Probability, Math, Calculus. I love teaching Statistics and Probability! Why me?
** I have experience in Statistics and Probability topics for middle school, high school and university.
** I always want to share my knowledge with my students and have a great relationship with them.
** I have experience working with students online.
** I am very patient with my students and highly committed with them
