Physics Photo of the Week
Warren Wilson College
Physics Photo of the Week is
published weekly during the academic year on Fridays by the Warren
Wilson College Physics
Department. These photos feature an interesting phenomena in
the world around us. Students, faculty, and others are invited to
submit digital (or film) photographs for publication and
explanation. Atmospheric phenomena are especially welcome.
Please send any photos to firstname.lastname@example.org.

The tangled power lines due to Tropical Storm Ivan prevented the
timely display of Physics Photo of the Week.
A Progress Energy worker is repairing the power lines near the
Notice the 3 orange flexible cables dangling
between the high voltage cables. These wires provide conductive
short circuits to prevent shock hazard to the utility workers in case
the power lines were to become inadvertantly activated. If the
lines were to become activitated, the electrical current would take a
"short-cut" through the short circuits, thus blowing a fuse and
de-activiting the lines and preventing serious injury to the electrical
workers should they come in contact with the lines.
Our sincere appreciation is expressed for the utility workers who come
out in bad weather to work under dangerous and hazardous conditions to
restore electrical power in a timely manner enabling us to enjoy our
basic services (refrigeration, water pumping,
lights, computers, TV/radio, and video games). Many thanks
to the electrical workers!
