Physics 201- Introduction to Electricity & Magnetism
October 18- Kirchoff's Rules






  A classmate says, "The relationship R= V/ I tells us that the resistance of a conductor is directly proportional to the potential difference applied to it."  How do you respond?

What is the current through a 100W light bulb that is plugged into the wall (120V difference)?  And, what is the resistance of the light bulb?
