When Benjamin Franklin said an object was "positively charged," he meant that it had ...

• ... no electrical fluid at all.

• ... an excess of electrical fluid.

• ... the highest amount of electrical fluid.

• ... less electrical fluid than usual.

In 1897, J.J. Thompson, working in Cambridge, England, discovered that the electrical fluid described by Franklin was actually made up of:

• A fluid much less dense than air, so it's stored in clouds

• Bits of dust that combined their energy

• Small particles later named electrons

• Stones, named after the physicist George Stoney
