Amp
An amp was a unit of measurement for an electric current.

In 2368, William T. Riker questioned if Data's body could withstand a half a million amps would flowed it as a nonconductor. Data indicated that such a power surge would cause a system failure in his internal processors and melt his primary power couplings. ()

In 2374, the miniature Miles O'Brien warned the miniature Julian Bashir, who were both inside an optronic circuit, not to touch a nearby chip because it carried 20 microamps of electric current, which normally wasn't very much, but would be sufficient to fry every synapse in the body of a person who was only one centimeter tall.
