If one lamp of a group of five identical lamps in series is removed, the voltage across the empty socket becomes equal to the line voltage, rather than remaining one-fifth of it. Why ?
Homework Answers
The voltage across a conductor can be measured if the conductor is offering some resistance. In absence of lamp, the voltage across the lamp disappears and the voltage across remaing four lamps increases and is equal to one fourth of line voltage.
The voltage across anu conducor is given by
V=iR (R is resistance offered by the conductor and i is current flow)

A Investigation #11: Non-Identical Bulbs in Series and Parallel All of the circuits you have investigated so far have involved identical bulbs. If two bulbs are identical and one bulb is brighter, then the brighter bulb must have a larger current thru it. Furthermore, the larger current must be caused by a larger potential difference. In this investigation, you will study circuits for which the bulbs are not identical. We will illustrate that two Spherical bulbs are not identical by...

1 L, as a dynamical system (Notes from Assignment #2) We take our definition of dynamical system to be an "object" along with a specific set of modifications that can be performed (dynamically) upon this object. In this case, the object is a bi-infinite straight road with a lamp post at every street corner and a marked lamp (the position of the lamplighter). There are two possible types of modifications: the lamplighter can walk any distance in either direction from...
