1.   During contests he was as jumpy as a schoolgirl and gave off a static charge of nervous energy.

2.   And when a static charge builds on a metal surface, generally it stays there.

3.   Agfa, for instance, adds a layer of conducting polymers to its photographic film to drain away static charge that might otherwise ruin the film.

4.   Cloths with synthetic fibers are less absorbent and can produce a static charge that repels dust away from the cloth.

5.   In the recent maintenance visit, workers were checking the connections that prevent static charges from building up in the tanks.

6.   One was that a pipe inside the tank, filled with fuel under pressure, sprang a leak and created a spray, which built up a static charge.

7.   Some helicopters have caught fire from static charges created as fuel trickled back into tanks through vent tubes, said a senior FAA engineer specializing in fuel systems.

8.   Static charges are often cited as the triggering event in fuel explosions when they cannot otherwise be explained.

9.   The experiment revealed that static electrical charges on the surfaces of dust particles draw them into clouds.

10.   The spray would have built up a static charge.
