The current is determined by the resistance.

You left voltage out of the picture. The basic power formula states P=IV. High current coupled with a moderatly high voltage can cause great damage. I work with with 480vac circuits and pay them great respect.

One more point as to current and resistance. An average car battery can crank out ninety amps or better at 12 vdc. You would be hard pressed to even feel it if you touched both posts. 277 vac at even 10 amps would tend to ruin your day.
