Question:

In an old house, the wires leading to a $120 \mathrm{~V}$ outlet have a total resistance of $0.45 \Omega$. When you plug in a hair dryer, it draws a 12 A current.

a. How much does the outlet voltage decrease due to the voltage drop across the wires?

b. What is the power dissipated as heat in the wires?
