Consider the classic problem with holiday lights, one little bulb goes out and the whole string goes out. First consider a string of 50 lights in series that plugs into a standard 120VAC outlet and consumes 40 Watts of power.
a. What is the current flowing through each bulb?
b. What is the voltage drop across each bulb?
c. If when a lightbulb burns out the resistance of the bulb becomes infinite, what is the current flowing through that bulb? What is the current flowing through the entire circuit?
d. If a bulb breaks open, exposing the two wires inside and they touch together (i. e., on) what would be the current flowing through this "short circuit"?
e. If the bulbs were instead wired in parallel and a bulb broke open and shorted, what would be the current flowing this short circuit?
f. Which configuration is safer, series or parallel? Why?
