Electrical terms that Benjamin Franklin appears to have been the first to use, at least in print in English:

• armature
• battery
• brush
• charged
• charging
• condense
• conductor
• discharge
• electrical fire
• electrical shock
• electrician

• Leyden bottle
• minus (negative or negatively)

This list is from Carl Van Doren’s 1938 biography. “Though he never lost sight of what was being done in electricity during his whole lifetime, he was perfectly willing to have his contributions to it absorbed in the enlarging science. They were absorbed, and it is now difficult to trace the details of his influence.”
