PHYS345 Electricity and Electronics

Hint for 2.38

As mentioned on the errata page, I believe that the load should be characterized as 5 ohm, rather than 5 W. Although loads are often characterized by the power they dissipate when connected to a 115 ac source, it is unusual to see it characterized this way for an arbitrary voltage. Also, notice that part b) asks what happens when the load is changed to 10 ohm.
